Abstract
We have studied the magnetization of high critical
temperature superconductors YBa2Cu3O
. Measurements
were made using a vibrating sample magnetometer technique. Several
magnetization hysteresis cycles have been obtained for different angles,
, 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".
