TRANSPORT JC(B,T) AND FLUX PINNING BEHAVIOR IN MELT-TEXTURED BI-SR-CA-CU-O HIGH-T(C) SUPERCONDUCTORS
The magnetic field dependence of the transport critical current densities (Jc) in the temperature range 20-70 K has been measured on melt-textured Bi-Sr-Ca-Cu-O samples. Jc decreased approximately exponentially with magnetic field. The characteristic magnetic field B*, determined as the magnetic fie...
