摘要：

The magnetization properties of Bi-2212 single crystals were measured by local Hall probe magnetometry (LHPM). Features characteristic of the Bean-Livingston surface barrier were observed. The lower critical field H(c1) was determined by considering the effect of the surface barrier on the magnetization. The temperature variation of H(c1) shows saturation at low temperature which is consistent with the prediction based on the BCS theory.
