โœฆ Synopsis

A wide variety of superconducting oxides are used to test a general model of high-pressure-induced transition temperature (To) changes. The Tc vary from a low of 24 K to a high of 164 K. Although the model is capable of predicting both increases and decreases in Tc with pressure, only superconductors that exhibit an increase are considered at this time. Predictions are made of the maximum T~, for 15 superconductors as a function of their compressibilities. The theoretical results generally agree well with experiment. This model of Tc as a function of pressure is derived from a recent successful phenomenological theory of short coherence length superconductivity.

A general calculation of high-pressure-induced transition temperature (T,) increases for oxide superconductors gives a good description for the Hg-Ba-Ca-Cu-0 system. Predictions are made of the maximum Ts u \_ 163, 154, and 111 K compared with Ty = 164,154, and 118 K respectively for the superconduc
