The first magnetic penetration field in Bscco single crystals temperature dependence and electron irradiation effect

Conference:

Abstract

We report measurements of the first magnetic penetration field, H{sub p}, of Bi{sub 2.2}Sr{sub 1.8}Ca Cu{sub 2}O{sub 8+{delta}} crystals by a novel local Hall probe technique. We demonstrate that H{sub p} is slightly enhanced above the thermodynamic lower critical field, H{sub c1}, by the Bean-Livingston surface barrier, and that irreversible magnetization at temperatures between 50K and T{sub c} (87.8K) arises mainly from the presence of this barrier. We argue that the non-linear temperature variation of H{sub p} observed, results from a temperature-dependent efficiency of the Bean-Livingston barrier.
