Critical Currents of 85K Bi--Sr--Ca--Cu--O

Critical current densities of pressed and sintered pellets of Bi--Sr--Ca--Cu--O are reported, as measured by transport current and magnetometer. For a sample sintered at 860 deg C, the critical current density inferred from the magnetization was 40 times greater than the measured transport current d...

Description
Summary:Critical current densities of pressed and sintered pellets of Bi--Sr--Ca--Cu--O are reported, as measured by transport current and magnetometer. For a sample sintered at 860 deg C, the critical current density inferred from the magnetization was 40 times greater than the measured transport current density. This result, and comparison with the magnetization of a crushed pellet, indicate that the effects of granularity are as severe as in polycrystalline YBa sub 2 Cu sub 3 O sub 7 . 9 ref.--AA
