Abstract Using finite-element analysis in a self-consistent way with the self-field of the current considered for superconducting thin film, the field and current distributions under partial field penetration are calculated based on the field dependent critical current density function. The field penetrated depth is non-linear with the applied field. Due to the limited resolution of the vibrating sample magnetometer (VSM), the full penetrated field measured by VSM may be much smaller than its actual value.
