We estimated Jc-B characteristics based on the sand-pile model from the magnetic field distribution on large disk samples with dimensions of 10 × 10 × 1 mm3. Such thin disks show a large demagnetizing effect. Thus simple estimates of Jc from the field distribution failed to determine correct values, and a large discrepancy was observed with Jc values determined from magnetization loops of small specimens. Jc-B characteristics obtained from the sand-pile model were in good agreement with those obtained from small specimens.
