Abstract

The first field for magnetic flux penetration H in Bi(2)Sr(2)CaCu(2)O(8+delta) (Bi-2212) single crystals near the critical temperature T(c) was investigated from the local magnetic hysteresis loops registered for different magnetic field H sweeping rates by using a scanning Hall probe microscope (SHPM) with similar to 1 mu m effective spatial resolution. Evidences for a significant role of the surface barrier were obtained: the asymmetric shape of the magnetization loops and an anomalous change in the slope of H(p)(T) close to T(c).
