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 λs > 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 λs < 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.
