Abstract
Pressure dependence of the superconducting transition temperature T c and the lattice parameter for high-T c oxides is discussed on the basis of Cyrot's model in which T c is proportional to t 2/U (t is the transfer integral and U the intraatomic Coulomb repulsion). The relation between dT c/dP and K v T c (K v is the volume compressibility) is examined in connection with the emperical relation found for magnetic compounds with an antiferromagnetic superexchange interaction in which T N is proportional to t 2/U.Keywords
