Abstract

Peculiarities of the structure, magnetic properties, and temperature dependence of magnetoimpedance effect of a Fe₂₀Co₆Ni₇₄/Cu₉₈Be₂ composite wire with the induced axial magnetic anisotropy are studied in this work. The increase in the temperature in a range from 150 to 450 K is shown to lead to an increase in the magnetoimpedance effect. To explain the experimental results, a model is proposed, which takes temperature variations of the magnetization and magnetic anisotropy constant of the Fe₂₀Co₆Ni₇₄ magnetic layer into account.

感应磁各向异性的复合线磁阻效应的温度依赖性

摘要

本文研究了具有感应轴向磁各向异性的Fe ₂₀ Co ₆ Ni ₇₄ / Cu ₉₈ Be ₂复合线材的结构特点，磁性能和磁阻抗效应的温度依赖性。温度在150至450 K范围内的升高表明会导致磁阻效应的提高。为了解释实验结果，提出了一个模型，该模型考虑了Fe ₂₀ Co ₆ Ni ₇₄磁性层的磁化温度变化和磁各向异性常数。
