Abstract

The interaction of the ribbon surface with acetone and its effect on the magnetic characteristics of ribbon are studied in this work using the example of soft magnetic Co-based AMAG-172 (Co–Ni–Fe–Cr–Mn–Si–B) amorphous alloy. The studies show the different effect of acetone treatment of ribbon on the magnetization distribution and magnetic permeability of material in states differing in the sign of saturation magnetostriction. The treatment of the ribbon in the state with λ_s > 0 favors the increase in both the volume of domains with the orthogonal magnetization and the magnetic texture sharpness in the ribbon plane; in the state with λ_s < 0, the treatment favors the decrease in both the volume of domains with the orthogonal magnetization and magnetic texture sharpness and an increase in the maximum magnetic permeability. This can result from the predominantly planar anisotropic compressive stresses induced in the ribbon by catalytic oxidation and hydrogenation of acetone.

化学活性介质对软磁钴基非晶合金磁性能的影响

摘要

本文以软磁性钴基AMAG-172（Co–Ni–Fe–Cr–Mn–Si–B）非晶态为例，研究了带状表面与丙酮的相互作用及其对带状磁性的影响。合金。研究表明，在饱和磁致伸缩符号不同的状态下，丙酮处理碳带对材料的磁化分布和磁导率具有不同的影响。带的在状态λ治疗_小号> 0有利于增加与正交磁化，并在带平面中的磁纹理锐度域两者的体积; 在λs_的状态<0，该处理有利于减小具有正交磁化强度和磁织构锐度的畴的体积，以及增加最大磁导率。这可能是由于丙酮的催化氧化和氢化作用在带中产生的主要为平面的各向异性压应力引起的。
