Critical currents in bulk [formula omitted] composites

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 J c( T) are presented. The best agreement of experimental J c( T) with theory has been reached for the Günsenheimer-Schussler...

Description
Summary: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 J c( T) are presented. The best agreement of experimental J c( T) with theory has been reached for the Günsenheimer-Schussler-Kümmel consideration of superconductor-normal metal-superconductor (SNS) junctions in the “clean” limit.
