Abstract

The temperature dependence of the AC magnetic susceptibility has been measured in the frequency range between 100 Hz and 40 kHz for various high-T_c supeconductors and analyzed on the basis of a model which incorporates the effects of flux creep in the critical-state equation. By a comparison of the experimental data with our theoretical model, the frequency-dependent shift of the intergranular energy-loss peak is explained quantitatively and the parameters pertaining to the flux-hopping frequency and pinning potential in the model are determined for various high-T_c superconductors.
