Title: Campbell penetration depth of a superconductor in the critical state.

Abstract

The magnetic penetration depth {lambda}(T,H{sub J}) was measured in the presence of a slowly relaxing supercurrent j. In single crystal Bi{sub 2}Sr{sub 2}CaCu{sub 2}O{sub 8} below approximately 25 K, {lambda}(T,H{sub J}) is strongly hysteretic. We propose that the irreversibility arises from a shift of the vortex position within its pinning well as j changes. The Campbell length depends upon the ratio j/j{sub c} where j{sub c} is the critical current defined through the Labusch parameter. Similar effects were observed in other cuprates and in an organic superconductor.
