Abstract
The magnetic ac susceptibility of high-temperature superconductors is shown to obey some scaling relations.We try to ananlyse this behavior within the framework of a common nonlinear response function of mixed state.The derived equations for critical current and ac susceptibility (x(T)) agree with the scaling relations of experimental data.
