“…When choosing the material, an important point is the fact that the selection of heat treatment conditions allows one to form the ribbon states characterized by different signs of saturation magnetostriction without any changes in the elemental composition. The studies were performed using samples in the quenched (Q) state and after heat treatments (HTs) in air at 370 and 380°С, which form states differing in the sign of magnetostriction constant; the time of the isothermal holding being 10 and 40 min [13]. The magnetization curves were measured by the induction-pulse method.…”

“…The errors of measurements of the magnetic induction and magnetic field did not exceed 2% and the error of measurements of the maximum magnetic permeability did not exceed 3%. The magnetization distribution in the ribbon was determined by an original technique, which was developed by us, using the correlation dependence between the maximum values of residual induction (B rs ) and volume of domains with the orthogonal magnetization component, which was obtained by Mössbauer spectroscopy and measuring residual induction in minor hysteresis loops [13,14]. The relative error of determination of the magnetization distribution did not exceed 5%.…”

The performed studies showed that the treatment of a ribbon of soft magnetic Co-Ni-Fe-Cr-Mn-Si-B amorphous alloy with acetone affects the magnetic characteristics of the ribbon. The effect is different for the states of the ribbon differing in the sign of magnetostriction constant (λ s ). In the case of the state with λ s > 0, both the volume of domains with the orthogonal magnetization component and the sharpness of the in-plane magnetic texture increase; at λ s < 0, a decrease in the volume of domains with the orthogonal magnetization, a decrease in the sharpness of the in-plane magnetic texture, and an increase in the maximum magnetic permeability take place. The increase in the time of the treatment magnifies its effect on the volume component of magnetization and decreases the effect on the in-plane magnetization redistribution. This can be related to an increase in the level of compressive stresses induced by catalytic oxidation and hydrogenation of acetone.

“…The measurement errors of the magnetic induction and field strength did not exceed 2%; the measurement error of magnetic permeability did not exceed 3%. The volume of domains with orthogonal magnetization, which is the indirect characteristic of the level of internal stresses, was determined using the correlation dependence between the maximum values of the residual induction and volume of domains with an orthogonal magnetization component, which was obtained by Mössbauer studies [7,8]. The relative error of determination of the magnetization did not exceed 5%.…”

To ascertain opportunities for the optimization of magnetic properties of a cobalt-based soft magnetic amorphous alloy AMAG-172 (Co-Ni-Fe-Cr-Mn-Si-B) results of systematic studies of their nonuniformity in the as-quenched state are reported. The studies showed the existence of the substantial nonuniformity of magnetic characteristics both across the ribbon width and along the ribbon length. The nonuniformity of magnetic characteristics along the ribbon length is periodical in character and sinusoidal; this can be related to the manufacturing conditions of the ribbon. Variations of the maximum magnetic permeability and volume of domains with an orthogonal magnetization component are in antiphase. A bimodal field dependence of the magnetic permeability is found, which can result from the nonuniformity of the characteristics across the ribbon thickness.
