摘要：

Current-dependent kinetic inductance of superconducting thin films is studied experimentally. A measurement circuit for the precise measurement of the kinetic inductance is developed for this purpose. The voltage across an inductance made of YBaCuO meander line is measured as a function of applied current. From the nonlinear relationship between the voltage and the current measured in the experiment, dependence of the kinetic inductance on the current is obtained. The experimental results are consistent with the theoretical results predicted from the Ginzburg-Landau (GL) theory.
