  We have proposed a systematic theoretic framework to calculate the trapped
magnetic field and temperature distributions in a superconducting disk (SD)
magnetized by a field-cooling process. Our calculations are based on the
critical state model with temperature and field-dependent critical current
density, and the heat conduction equation with account of the heat produced by
flux motion. We distinguish the normal state region from the superconducting
state region. Our calculated results are in good agreement with the recently
experimental results reported by different groups, and the deviation is well
explained.
