摘要

我们提出了一个简单的模型来计算测量线圈局部交变磁场在超导薄膜中产生的电流分布。该模型同时考虑了径向和厚度的非均匀电流分布。得到了样品中电流密度峰值的空间分布，并根据驱动电流的幅值考虑了响应信号的频谱组成。将模型响应与实验数据进行了比较。

Two-Dimensional Model for Induction Current Distribution in a Superconducting Film

We present a simple model for calculating the distribution of the currents induced in a superconducting film by a local alternating magnetic field of a measuring coil. The model takes into account both radial and thickness nonuniform current distribution. The spatial distribution of the peak values of the current density in the sample is obtained, and the spectral composition of the response signal is considered depending on the amplitude of the drive current. The model response is compared with the experimental data.
