Abstract: Hydrostatic pressure studies on the tetragonal 123 superconductor (La1-xCax) (Ba1.75-xLa0.25+x)Cu3Oy for x =0.1 and variable oxygen content y show that increases rapidly under pressure (+5 K/GPa) for underdoped, optimally doped and overdoped samples. This points to a common cause for the pressure-induced changes in the superconductivity at all levels of doping, with negligible effects from charge transfer. Weak relaxation behavior in is observed only for the most underdoped sample.
