Dissipation Power of a Disk-Shaped Superconducting Thin Film Along Its Virgin Magnetization Curves

Based on the Bean critical state model j≤ j_c, for both longitudinal and transverse geometry, the total dissipation power P along the virgin magnetization curves is calculated. The dissipation power obtained from the corresponding magnetic measurements for a disk-shaped YBa₂Cu₃O_7-σ thin film in a perpendicular magnetic field is verified. The virgin magnetization curves for the sample at different temperatures are calculated.
