The AC loss and the real part of the AC permeability at low frequency and low magnetic field were measured for a sintered polycrystalline Y-Ba-Cu-O sample. The dependence on the AC amplitude and a superimposed DC magnetic field is explained in terms of a critical state model which accounts for the i
