High-Temperature Superconductors

As far as I remember, there was an odd breakthrough made about 10 years ago involving a sort of weird amalgam/quasi-ceramic that contained several rare earth elements that provided superconducting capabilities at liquid nitrogen temperatures. You could even get a little kit from Edmund Scientific that would levitate a rare-earth magnet over a disk of this stuff that was submerged in liquid nitrogen. Other than that, not much has appeared.

Note that the superconducting process of these "high-temp" superconductors use is quite different than those involved in superconductors that act at about 3° above absolute zero (e.g.; lead). Also, the high temp superconductors are very brittle and very difficult to work with. For instance, one could not make any kind of a good wire out of these materials.

That's about it thus far.
