We made this super conductor at work, it's Yttrium, Barium, and Copper I believe(There's an element chart attached from our Electron Microscope, along with some Electron Microscope pictures of it.)
It's sitting in liquid nitrogen, to get it very cold, as it has to be very cold to work. The videos are pretty cool, especially the one called "clock" with the spinning disk magnet and the ones where the magnet is being moved by another magnet that's under the table. This was pretty fun to do.
I think liquid nitrogen is somewhere in the area of -180 degrees. Can't remember if that's in fahrenheit or celcius though.
Hmmm, wiki says the following:

Further, its ability to maintain temperatures far below the freezing point of water (it boils at 77 K, which equals -196 °C or -320 °F) makes it extremely useful in a wide range of applications as an open-cycle refrigerant, including
Hybrid Mode
