The frequency f and amplitude B-0 of applied magnetic field dependence of the loss behavior in the liquid nitrogen region is studied in high temperature superconducting slabs. The magnetothermal diffusion equations based on the power-law model are presented in this paper to estimate the effect of f and B-0 on the loss. Numerical results obtained show that, generally, the loss is proportional to B-0(3) in the nonpenetration field and to B-0 in the penetration field, and the loss power is proportional to f whether the magnetic field penetrates it or not.
