Abstract

The pressure effect on the superconducting transition temperature T_c of the newly stabilized YSr₂Cu_2.8Mo_0.2O_y and TbSr₂Cu_2.7Mo_0.3O_y compounds has been examined under hydrostatic pressure. The pressure coefficient dT_c/dP was found to be+0.84 K/kbar for YSr₂Cu_2.8Mo_0.2O_y and +0.4 K/kbar for TbSr₂Cu_2.7Mo_0.3O_y. These large positive values of dT_c/dP suggest that the presence of Mo in the CuO-chain sites is crucial in the stabilization of the Sr-based 123 compounds.
