Revisiting Low-Frequency Susceptibility Data in Superconducting Materials

By Jacob Szeftel, Michel Abou Ghantous, and Nicolas Sandeau
Progress In Electromagnetics Research Letters, Vol. 81, 1-8, 2019


Old susceptibility data, measured in superconducting materials at low-frequency, are shown to be accounted for consistently within the framework of a recently published [1] analysis of the skin effect. Their main merit is to emphasize the significance of the skin-depth measurements, performed just beneath the critical temperature Tc, in order to disprove an assumption, which thwarted any understanding of the skin-depth data, achieved so far by conventional high-frequency methods, so that those data might, from now on, give access to the temperature dependence of the concentration of superconducting electrons.
