摘要

摘要研究了电流分布不均匀的磁性结构中的巨磁阻效应。一种特殊的设计降低了结构外的固有磁场的大小。我们从理论和实验两方面研究了这种由具有径向电流分布的磁性软材料制成的平面结构的磁阻。理论评估显示，结构的阻抗随频率和材料的磁导率值变化很大。模型样品的实验数据定性地证实了计算结果。

Impedance of Structures with Non-uniform Current Distribution

Abstract

The effect of giant magnetoimpedance in magnetic structure with inhomogeneous electric current distribution is studied. A special design reduces the magnitude of the intrinsic magnetic field outside the structure. The magnetoimpedance of such a planar structure made of magnetically soft material with radial current distribution has been investigated both theoretically and experimentally. The theoretical evaluations show a strong variation of the impedance of the structure with the frequency and the permeability value of the material. The results of calculations are qualitatively confirmed by experimental data for model samples.
