Effect of Ag₂O Doping on Some Physical Properties Y145 Superconductor

Abstract

In this paper, the Y145 superconductor doped Ag2O were synthesized by solid state reaction. The calcinations and sintering temperature were at 920 °C and annealing temperature was at 550 °C. The highest critical temperature was in Y145+0.1Ag sample with Tc onset at 96 K and the lowest was found in pure Y145 at 95 K. We found that the surface of Y145 superconductor was improved by Ag adding on the porous structure.
