根据非晶态Fe_5Co_(73)Si_(10)B_(12)合金薄带不同方向磁化曲线与磁致伸缩曲线随退火状态的变化规律,发现Curie温度低于晶化温度的非晶态合金经旋转磁场热处理时,可以消除由于自发磁化场所感生的磁各向异性。初步分析和讨论了淬火态(制备)非晶态合金具有磁各向异性的原因。
According to the variation law of magnetization curve and magnetostrictive curve with annealing state of amorphous Fe_5Co_ (73) Si_ (10) B_ (12) alloy ribbons, it is found that the amorphous alloy with Curie temperature lower than the crystallization temperature is rotated During magnetic field heat treatment, magnetic anisotropy induced by spontaneous magnetization can be eliminated. The reasons for the magnetic anisotropy of quenched (prepared) amorphous alloys were analyzed and discussed.
