摘要

Based on the Bean critical state model j ≤ jc for both longitudinal and transverse geometry, the total dissipation power P along the virgin magnetization curves is calculated. The dissipation power obtained from the corre sponding magnetic measurements for a disk-shaped YBa2Cu3O7-δ thin film in a perpendicular magnetic field is verified. The virgin magnetization curves for the sample at different temperatures are calculated.
