Abstract

The effect of high pressure and high temperature on electrical resistivity behavior of (Nd, Eu, Gd) Ba-Cu-O superconductor with 10wt %Ag2O addition was studied. This high Tc superconductor was synthesized using the oxygen controlled melt growth process(OCMG).At room temperature ,there was an initial drop in the resistivity of the superconductor up to 3GPa ,followed by a nearly constant value up to 8GPa pressure. The steady value of resistivity observed between 3 and 8GPa decreased with increasing Ag2O content. The superconducting composite formed exhibited a metallic nature under pressure up to 8GPa.
