We have measured the magnetization and the heat capacity of over-doped (OVD) and optimally doped (OPD) BiESr2CaCu2Oy single crystals in the mixed state under magnetic fields applied along the c-axis. In both samples, a distinct magnetization step is observed in the magnetization curve at high temper
