Abstract
We have recently shownl that magnetic torque is a very powerful tool to investigate flux creep in the new sintered high Tc superconducting perovskites. It has become clear2,3,4 that these materials behave as weak coupled superconducting grains. Flux pinning and creep have been reportedl at moderate fields (10 G < H < 10 kG) at which grains become independent.
