Abstract

Pressure dependence of magnetization has been investigated in two La-based ternary germanides La₃Ir₂Ge₂ and La₃Rh₂Ge₂. La₃Ir₂Ge₂ was found to be a new superconductor of a critical temperature T_c = 4.7 K, and La₃Rh₂Ge₂ was a type-II superconductor with T_c = 3.5 K. Detailed measurements of magnetization and AC susceptibility in the region of the applied magnetic field up to 1 T and hydrostatic pressure up to 1 GPa were performed. The pressure-temperature phase diagram of La₃Ir₂Ge₂ was obtained. We discuss pressure dependence of the superconducting temperature in these materials.
