摘要

当前从事非晶态合金丝巨磁阻抗效应的理论研究均以忽略其内部退磁场为前提, 该前提对于小尺寸非晶态合金丝不适用. 本文提出一种用于计算CoFe-基非晶态合金丝内部静磁化强度、退磁场分布的模型. 该模型将非晶态合金丝内部划分成同轴、等宽、等厚、半径不同的相邻无交圆环, 计算各圆环内磁化强度对场点r处退磁场冲激响应, 得到冲激响应矩阵. 利用该矩阵求解均匀/非均匀直流偏置磁场中非晶态合金丝内静磁化强度、退磁场分布.

Abstract

Currently, the giant magneto-impedance effect of amorphous wires is usually investigated on the hypothesis that demagnetizing field can be ignored. This hypothesis is not true for amorphous wires with small size. We propose a model for calculating the static magnetization and magnetic field distribution inside CoFe-rich amorphous wires, which divides the amorphous wire into coaxial and nonoverlaped circular rings with the same width and height and different radii. Calculating the impulse response of the demagnetizing field at point r to the magnetization in each ring, the impulse response matrix is obtained. Using the impulse response matrix, the static magnetization and demagnetizing field distribution in the amorphous wire placed in an uniform or non-uniform DC applied field can be obtained.
