Critical currents in bulk Y {3}/{4}Lu {1}/{4}Ba 2Cu 3O 7 + BaPbO 3 composites
Abstract
Bulk composites Y {3}/{4}Lu {1}/{4}Ba 2Cu 3O 7 + BaPbO 3 with BaPbO 3 volume content of 0-60% have been prepared. Temperature dependences of resistance and critical current density Jc( T) are presented. The best agreement of experimental Jc( T) with theory has been reached for the Günsenheimer-Schussler-Kümmel consideration of superconductor-normal metal-superconductor (SNS) junctions in the “clean” limit.
