Abstract

Superconductivity is the ability of certain material to conduct electric current with no resistance and low losses. High temperature superconductor, such as YBa2Cu3o7·x (Tc=90K), were discovered in 1987 and have been actively studied since. The universally known fact about superconductivity is that below some characteristic transition temperature (Tc) many metals exhibit a complete lack of electrical resistance to a flow of direct current. Such a lossless 'super current' can be set up around a close loop of superconducting wire, there being no detectable decay with time (with a half· life shown experimentally to be at least 10' years). This complete loss of resistance was first observed by Onnes (1911) for the metal mercury for which Tc=4.19K, close to the normal boiling point of liquid helium. The latter had been liquefied for the first time only shortly before in the same laboratory, thus opening up a new field of cryogenics.
