Abstract
Magnetization measurements have been performed for the newly found superconductor, BiSrCaCu2O x , which is composed of two phases, i.e., a high-T c phase (105 K) and a low-T c phase (75 K). The superconductor is found to be of type II and the lower critical field of the high-T c phase is as small as 16.2 Oe at 77 K. The volume fraction of the high-T c phase is as high as 21% in the present sample. The hysteresis observed in the magnetization vs field curve is much smaller in BiSrCaCu2O x than in YBa2Cu3O y , implying a small critical current density in the high-T c phase.Keywords
