The recent discovery of the Y-Li-Sr/Ba-Cu Oxides, Thallium, and other superconducting compounds (Ln2.?Ce?Cu04.y (Ln=Pr,Nd,Sm) ) has significantly raised the operating temperatures required for superconductivity to levels above 90*K (-183*C) , where easily obtainable and inexpensive liquid nitrogen can be employed to cool and maintain the material in a superconductive state. The present goal of superconductor researchers is to attain a room temperature (or higher) superconductor. Ideally, the superconductive temperature should be high enough to permit the extraction of heat or light from the superconductive circuit (e.g., the operating temperature of filaments in incandescent light bulbs) , thereby accommodating common needs in everyday society.
