The magnetic field and temperature dependencies of dispersive and absorption components of low frequency dynamic susceptibility for some bismuth and thallium based ceramic high-temperature supeconductors as well as for a bismuth single crystal have been measured and analysed. These physical properties differ considerably from those of conventional low temperature superconductors. The changes are due to the influence of the integrain microstructure which dominates the low magnetic field behaviour and the integrain behaviour at higher magnetic field. Critical current densities have been extracted from comparison of the experimental data with the superconducting critical state model.
