摘要: 本文研究了金属玻璃(Fe1-xCOx)78Si10B12的磁化感生各向异性、应变感生各向异性随成分和温度的变化。磁化感生各向异性常数Kum为正值,x=0.7时为最大;不可逆的应变感生各向异性常数Kusi为正值,x=0.5时为最大;可逆的应变感生各向异性常数Kusr除了x>0.975区均为负值,在x=0.7时为最大;感生各向异性常数在温度变化时与Msα成正比,α在3.4和7.5之间随成分和退火工艺而变化。用短程有序模型解释了部分实验结果。

Abstract: The variations of magnetization- and strain-induced anisotropy in metallic glasses (Fe1-xCox)78Si10B12 with composition and temperature have been studied. The magnetization- and the irreversible strain-induced anisotropy constants, Kam and Kusi, have positive values, the maximums of which occur at x=0.7 and 0.5 respectively. The reversible strain-induced anisotropy constant Kusr has a negative value except for x>0.975, the magnitude of which exhibits a maximum at x=0.7. As to the temperature dependence of Ku, a common relation Ku(T)=kMsα(T) is followed, in which a is a constant between 3.4 and 7.5 depending on the composition and the annealing condition used. Some of the experimental results are explained by using the concept of short range ordering.
