Abstract
We have studied the magnetization of high critical temperature superconductors YBa₂Cu₃O $_{7\hbox{-}\delta}$ . Measurements were made using a vibrating sample magnetometer technique. Several magnetization hysteresis cycles have been obtained for different angles, $\theta$ , between the applied magnetic field, H, and the crystallographic c-axis. For T = 30 K we observed a central peak and for T = 80 K we observed a second peak or "fishtail".
