<正> 急冷法制备的非晶软磁材料的实用磁性与其磁各向异性和磁矩取向分布密切相关。大量研究表明,急冷状态的过渡金属-类金属非晶合金薄带里的磁畴结构和磁矩取向主要取决于淬火急冷内应力。Becker通过磁化测量发现,表面层去除和厚度减薄对急冷内应力系统没有影响。Takahashi等的磁转矩研究表明,急冷态非晶薄带2个表面附近的磁各向异性最大。对急冷态非晶薄带的Moss-bauer研究表明,磁矩取向主要分布在薄带平
Magnetic anisotropy and distribution of moments in the ribbon of rapidly quenchedamorphous alloy Fe_(81)B_(13.5)Si_(3.5)C_2 have been studied with~57Fe Mossbauer effect. The results showthat thinning and surface removing of ribbons have little influence on the internal stress systemand distribution of moments in as-quenched sample, and the distribution of moments does notvary along the thickness of the ribbon.
