We report the observation of an anomalous magnetization behavior in single crystal of Bi2Sr2CaCu2Os+y near the transition temperature after 200 MeV Ag ion irradiation with a fluence of 2.5 ร 1011 ions/cm 2. We argue that the magnetization anomaly (the virgin curve lying above the return leg and the
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 Hc~ was determined by considering the effect of the surface barrier on the magnetizati
