本文详细研究了铁基、铁镍基和钴基非晶合金条带制备态的平面磁各问异性。测定了退火前后试样中各向异性的变化及各向异性常数K_(us)随温度的变化,得出K_(us)(T)∝M_s~2(T)关系,由此得出平面磁各向异性由应力各向异性和表面形状各向异性两部分组成。
The in-plane magnetic anisotropy of as-quenched Fe-base, FeNi-baseand Co-base amorphous alloy ribbons has been studied. The variation of anisotropywith stress relief annealing and the magnetization square dependence on anisotropyconstant were determined. It was found that the in-plane magnetic anisotropy con-sists of two components, i. e., one related to the coupling between magnetostrictionand stress, and the other originated from surface shape effect.
