摘要

利用直流焦耳热加应力和不加应力退火处理Fe73 .5Cu1Nb3 Si13 .5B9非晶合金

并用动态磁滞回线、穆斯堡尔谱和纵向驱动巨磁阻抗效应等方法进行研究。结果表明

在电流密度大于 4 .11× 10 7A/m2 时

Fe73 .5Cu1Nb3 Si13 .5B9非晶合金发生晶化

并在应力退火下产生横向磁结构。在一定的条件下

感生各向异性随电流密度的增大而增大

这与合金中α -FeSi纳米晶粒的多少有着密切的关系。

Abstract

Amorphous Fe 73.5Cu 1Nb 3Si 13.5B 9 alloy was annealed under stress by DC Joule-heating to induce magnetic anisotropy. The magnetic properties of the treated samples were examined by dynamic hystersis loops

longitudinally driven giant magneto-impedance effect and Mssbauer spectra. The experimental results show that nanocrystallization occurs in the amorphous alloys when the current density is above 4.11×10 7A/m 2

and the annealed samples will be induced transverse magnetic anisotropy under suitable current and stress. The magnetic anisotropy increases with the increasing of annealing current density

which is closely related to the amount of α-FeSi nanocrstalline in the alloy.
