✦ Synopsis

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.

The complex mechanism of high-frequency dissipation in high-temperature superconductors is discussed. The dissipation is due to the presence of thermally excited carriers, vortex motion, and the existence of inter-and intragrain Josephson junctions in superconducting material. At a low magnetic fiel
