摘　　要：在非晶态合金材料中引入应力感生各向异性场及磁各向异性场,根据Maxwell方程组及带Gilbert项的Landau-Lifshitz方程,得到了能揭示非晶态合金材料应力阻抗效应的理论,理论结果可定性地解释实验结果.对不同各向异性场参数下的应力阻抗效应进行了大量计算,获得了一些对理论和应用具有一定参考价值的结论.The theory of stress-impedance effect in amorphous alloys was established by introducing stress-induced anisotropy and magnetic anisotropy and solving Maxwell＇s equations and Landau-Lifshitz equation with the Gilbert term. The established theory can be used to explain the stress-impedance effect, and the calculation results were in good agreement with the experimental results. We calculated the stress-impedance change with different anisotropy parameters, and reached important conclusions both in theory and for applications.
