MAGNETIC-FIELD DEPENDENCE OF THE TRANSPORT CRITICAL CURRENT-DENSITY IN MELT-TEXTURED BI-SR-CA-CU-O HIGH-TC SUPERCONDUCTORS
The transport critical current densities (Jc) in magnetic fields up to 14 T at 4.2 K have been measured on melt-textured Bi-Sr-Ca-Cu-O samples on MgO substrates. The samples were multiphase with partial alignment of the grains. Jc values of 1.58*104 A/cm2, 1.13*104 A/cm2 and 8.2*103 A/cm2were obtain...
