Critical Current Characteristics of YBa2Cu3O7-x-Ag Composite

Abstract
Silver powder was mixed with a Y-Ba-Cu-O superconductor so as to improve its critical current density, J c. The J c of YBa2Cu3O7-x with silver (3 wt%) was twice that without silver. T c (end point) was almost constant around 90 K in spite of the silver mix. The decrease of T c (end point) with magnetic flux was greatly inhibited by the silver mixing.
