采用趋近饱和定律首次测定了纳米晶合金环形试样有效磁各向异性常数〈K〉.为了对比测量的准确度,同时测试了传统的晶态坡莫合金环形试样的磁晶各向异性.结果表明,用环形试样可以完成对低矫顽力的软磁材料进行磁各向异性的测定.

By means of the law of approach to saturation,the effective magnetic anisotropy 〈K〉 of nanocrystalline alloys was first investigated using ring-shaped samples. To compare with conventional soft magnetic materials,the magnetic crystal anisotropy K1 of permalloy was also measured. The results show that the magnetic anisotropy of soft magnetic materials with very low coercive force can be measured successfully with ring-shaped sample according to the law of approach to saturation.
