Because there is a slight inaccuacy in calling it flux pinning. In short: type 2 superconductor have 3 states : *not superconducting and letting magnetic flux through. *superconducting and exhibiting the meisner effect like type 1 superconductors *"Abrikosov stage" where magnetic flux penetrates the superconductor, but around each penetration point there are created internal current vortecis which canel the feild that has penetrated. Imagine a rectangular slab in external nagbetuc feild and narrow needles of this magnetic feild penetrare the slab, around each needle there are created internal current vortecies to cancel the magneric feild. However pinning is thing that exists in superconductors. Imagine you pass currebt through a superconductor in this abrikosov stage - you will have Lorentz force acting on these vortecies, they would want to move however because of crystal defects and such they will be pinned in place and not move. Until you apply a string enough current to make these vortecies to creep, they will create EMF effectively acting as resistance.

YBCO is highly anisotropic, so it carries current only in one crystallographic plane. Grain boundaries or other perturbations in the lattice will kill your critical current instantly. This is why Powders in cables didn't work historically and wires from YBCO are now made as highly textured coatings on buffered tapes so the current carrying plane stretches throughout the tape.

You could still buy the tape if you dont't need long lengths it might not be too expensive.

Whats your take on making liquid Hydrogen though?

At this process the citric acid is a gelatin agent, means it creates strong chemical bonds with metal cations forming homogeneous gel kind of thing. this gel keeps homogeneity of matter till ignition. If u take just oxides or hydroxides of metals u will never get chemically homogeneous material since each metal has unique pH of crystallization from solution. If u use dissolved mixture of different nitrates with different decomposition temperatures and different solubilities u will get something inhomogeneous, clear. The second reason of the use of cit acid is to speed up the reaction due to increase the temperature since u have to "froze" metastable structure of amorphous oxides mixture to get proper material.

You can make a furnace/kiln for less than $100. 3. The hydraulic press isn't really necessary, but you can also make one for cheap if you want. 4. Buy a liquid nitrogen dewar ($200-300) and look for someplace where you can get LN2 or get a cryocooler (Ben got it for $400, though I can't find any). This is probably the most difficult and expensive step!

Just because I did not tell you "what and how" does not make me a liar and so in that spirit I'll also say this. Lithium Batteries are free every single day for anyone in this country and if you know "why, how and where" then just apply that thinking to your nitrogen dilema and voila! Personally all this super-conductor crap is a joke and nowhere near as interesting as...say....uhhmmmm a Bedini wheel (any of the hundreds he made). Or how about a complete GEET system?

We made one of these superconductors is physics class when i was in high school in the 80s. We used the mixing chemical method, not the pyro method and after a few tries we got one to work. I remember that the quantity of the chemicals had to be exact and mixed perfectly. We built a computer controlled kiln where a computer program monitored the output of the thermocouple that was placed near the sample. The computer just switched on and off the mains power to the kiln to allow for a perfect programmed temperature profile. The software took into account the thermal interia of the kiln and switch the power in such a way as the temperature drop was very gradule. From memory, we did the bake at one temp, drop to another and hold and then it reduced the temp right down to room temp at a gradual rate over a day or two. Your experiment really brings back some memories.

Ben is a genius. I remember doing experiments with high temp superconductors many years ago and I was struggling to make my own ultra sensitive low noise amplifier trying to measure the voltage drop.

Judging from the video, your shake and bake SC might not have failed! The superconductor seems to repel the magnet, consistent with Meissner repulsion. On a science show I was part of, we demonstrated a commercial grade YBCO slab, and the trick is to lower the SC below it's transition temperature with the magnet close by, separated by a paper spacer. This way the flux channels penetrate all the way through the superconductor, but are pinned on the crystal defects. Flux pinning where you set the magnet, and it stays there only works for very thin or very bad superconductors. The thin ones because the field can easily completely destroy the superconductivity in the flux channels since they aren't very long, and the bad superconductors since there is enough non-superconducting junk that the field can pass through so it doesn't need to create long channels.

Great to see another video. And the great thing is it is about a topic which really interests me since I've heard about it!

This takes me back, I spent a long year making variations on a theme of YBCO (everyone I worked with called it "ibco" btw). For attaching wires we used a platinum ink to stick on tiny pieces of platinum foil. Both were as expensive as you'd expect but a tiny bottle of ink lasted for hundreds of samples. You just paint a little ink on the sample, touch the platinum foil to it and then bake it in the furnace. I seem to recall the ink is platinum on carbon so the carbon burns away and the platinum sinters to the sample. I will say I was using this for high temperature experiments but I'm pretty sure it would work at low temperatures too. IIRC the methodology we used correctly you are cooking it way more than you need to. We'd just mix together stoichiometric amounts of material and chuck it in the furnace over night at about 1150 C - or lower than any of the components melting temperatures. The mixing process was grinding in a mortar and pestle then stamp it into disc using a 15 ton press. If you've got any questions I'm happy to try and remember what we used to do.

Thanks for your effort put in this video! I enjoy your work a lot. A good video in a long while is totally worth the wait!

It's worth noting that flux pinning occurs in perfect crystals as well, but for a different reason. In type-II superconductors like YBCO, sufficiently strong magnetic fields destroy the superconducting phase locally, even if it's below the critical temperature, essentially creating defects without actually altering the crystal structure of the material. The flux concentrates into thin tubes of high magnetic field, each containing one flux quantum, which, if you could measure them, would themselves form a two-dimensional crystalline pattern, a hexagonal lattice.

So cool! I always wanted to play with YBCO since it was discovered. Never did, and likely never will, but at least I got to play with it vicariously while watching your video.

I made 1/2/3 superconductors in high school chemistry. Fun times. Formed in a press, fired in a kiln, and frozen with LN2. Guidance to my teacher from Fermi. One of the best classes I had.

Nice. I've made YBaCuO in the 90s. I also wrote most of the data aquisition software and the heat treatment software. Some of that code is still in use, 20 years later.

the high-speed shot of the filings spinning the magnet looks so surreal, awesome

I've used a couple standard diodes for cryogenic temperature measuring and they were exact on 0.1 degree, highly linear. I've had a few, not all diodes work down to those temps but it's highly exact. You can judge the exactness based on the condensation points, that's also how you can normalize them.

Your videos are just simply amazing! Very interesting that this is even possible home made.

You amaze me in every new video, i did not even imagine that you can make a superconductor at home, or aerogel.

The process you're using to create the powder is sometimes called a 'sol-gel Pechini' process. The vapors during that burnoff phase can be dangerous and, since the process is exothermic, care must be taken to make relatively small batches in a laboratory setting or else it can run away and create a serious fire risk, including causing the beaker to break. Yea, I've had that happen. Corning 'visionware' 3.5 liter pots (with lids) actually work pretty well for demonstrations and are more durable.

Awesome video, really love your work! I assume you know this, and didn't go into the details for time, but its well worth pointing out when talking about pyrometric cones (even if only briefly), that they do not measure temperature directly, but measure heat work. Heat work can be related roughly as time and temperature. What is most significant, for those not familiar, is that you can, given changes in time, reach the same heat work (and by extension, the same deformation in the cone) at different temperatures.

Nice! I've actually made YBCO from the grinding method, we use a ball mill but if you heat it high enough for long enough I think it almost goes to a liquid stage and they mix intimately. Some people have issues with flowing oxygen in at room temp which brings the real temp down, and how fast you flow changes it proportionally. In a tube furnace thermocouple is on the outside of the tube so this is difficult to detect and a trial and error process but about 950 C worked for me. Our hold at 950 was longer than yours, maybe 6 hr

Hello! Great video! Just to collaborate a little bit, you could have used some 99% silver small leafs to calibrate the kiln. They melt at exactly 960°C and are sold for that purpose. I used to work in a laboratory at my university that tested electrical protections (such as RCCB's and thermomagnetics circuit breakers) and used this silver leaves to calibrate one device called "hot wire" to test the non-flammability of plastics used to manufacture this kind of electrical protections. Hope this helps!

This field of research has monumental potential. I have no doubt that room temperature superconductors are possible. Edison reputedly tried a thousand materials while searching for the best light bulb filament. Given that silver is one of the best room temperature conductors I think I'd want to try including traces of silver and/or silver oxide into the mix.

The genius talent and energy is found among the ordinary people and not necessarily within the confines of academia as Hoffer explains : Universities are an example of organizations dominated wholly by intellectuals; yet, outside pure science, they have not been an optimal milieu for the unfolding of creative talents. In neither art, music, literature, technology and social theory, nor planning have the Universities figured as originators or as seedbeds of new talents and energies. ~Eric Hoffer

Great video! You have all the cool toys.

We use the shake and bake method in adv. student labs. 20 mins of grinding and two bakes makes working superconductors 95% of time.

Amazing as usual. I liked your quick and easy air drier for the liquid air maker. BTW I was never able to use the original circuit to my liquid air maker because I screwed up the little coils that sensed the temperature, but I too used the Variac method. It seems like it would be easy to run too much current into the cooler unless you keep an eye on the voltage and current. Could you share some details on the voltage and current you use on the cooler.

I'm mega impressed. Wow.

That was a really cool video. Thanks

This video reminds me Cody’s lab. Great video thank you
