There have been reports of "anomalies" at about 240K in one of the new 90K superconductors: a compound of barium, yttrium, copper, and oxygen, I believe. The speculation is that there are two phases of the compound and that one is superconductive at 240K (-33 C -- not cold at all, really). I don't think anyone has isolated the pure 240K material (assuming it's real); it would be a pity if it exists but is unstable. -- - Joe Buck {hplabs,ihnp4,sun,ames}!oliveb!epimass!jbuck seismo!epiwrl!epimass!jbuck
