Using ac inductive method, magnetization curves of some high-Tc superconductors, ordinary ceramic YBCO and BPSCCO as well as melt processed YBCO, were obtained in the frequency range 10~500Hz with field amplitudes below 0.3T. Then ac losses were calculated as a function of a field amplitude and were discussed in terms of critical state model, granularity and flux diffusion.
