摘要：
Complex-susceptibility measurements of the superconducting transition of Tc films prepared by electrodeposition and reduction (heat treatment) have been performed. In order to find the optimum experimental conditions for preparation of metallic Tc by the present method, several different conditions have been attempted. For the measurement of the complex susceptibility, a Hartshorn-type mutual-inductance bridge was constructed. The whole performance of the measuring system was examined by using Sn and Pb films. It has been revealed that the structural details (dislocation or homogeneity) of the samples are well reflected on the observed complex susceptibility and that the mean energy dissipation in the temperature region of the superconducting transition is a good probe for structural examination of the samples. © 1979 The American Physical Society.
