“…The ac susceptibility measurements are based on an examination of the magnetic response of the sample immersed in an alternating field. This type of measurement [10] offers an opportunity to determine the frequency dependence of the complex ac susceptibility, which may provide relevant information about ac loss and flux dynamics in high-temperature superconducting samples. The complex permeability is an important parameter for studying ac loss [11], as its imaginary part is responsible for the losses due to the absorption of the ac field.…”

Impedances of a small solenoid were measured at different frequencies and temperatures both without and with a cylindrical sample of high-temperature superconductor (HTSC) material as the core. A parameter was derived from the measured values of and . was analysed and found to be proportional to the ac loss of the sample in the core. The temperature dependence of the ac loss was found to be in good agreement with the two-fluid model for different HTSC materials (ReBCO-type). The data could also be scaled successfully at two different temperature zones: below and above the critical temperature TC. It is also found that the temperature dependence of ac loss is dominated by two different characteristic temperatures in two different zones: below and above TC.

Dissipative effects near the transition temperature of high Tc superconductor

The complex magnetic susceptibility of oxide superconductors near the transition temperature has been computed as a function of temperature and frequency by numerical solution of the non linear, flux diffusion equation. For field values much lower than the upper critical field, a description of dissipative effects in terms of the conventional flux creep and flux flow pictures is not able to reproduce experimental data
