Magnetic properties of YBaCuO and BiSrCaCuO crystals: a comparative study of flux creep and irreversibility

We report strong, anisotropic magnetic relaxation for the zero-field-cooled magnetization of a BiSrCaCuO crystal measured with field H = 1 kOe parallel and perpendicular to the c axis. The relaxation rate increases with temperature, peaks at ⋍15 K and drops to zero at ⋍30 K , well below the transiti...
