Abstract

Neutron diffraction and magnetic susceptibility under high pressure show clear correlations between structural phase transitions and superconductivity in La_2-xBa_xCuO₄ with x=0.125. The bulk superconducting transition temperature T_c changes drastically at the pressures where the structural phase transitions take place. Characteristics of structure changes in the Sr-substituted system as well as under high pressure are presented.
