Abstract—Studies of soft magnetic Co-based amorphous alloy AMAG-172 (Co–Ni–Fe–Cr–Mn–Si–B) produced by different manufacturers show that, in the as-quenched state, the nonuniformity of magnetic characteristics across the width of ribbon produced in the PC MSTATOR (Borovichi) is substantially lower. However, the nonuniformity across the ribbon thickness takes place, which favors the formation of bimodal field dependence of the magnetic permeability. The stepped shape of initial portions of magnetization curves in the range of the first maximum of magnetic permeability and intermittent character of the magnetization processes in weak fields allow us to conclude that the formation of the first maximum in the field dependence for the ribbons produced in the PC MSTATOR is related to the independent magnetization reversal of the surface layer. The base layer of the ribbon participates in the formation of the second maximum. In the case of samples manufactured in the JSC NIIMET, the smoothed shape of stepped initial portion of the magnetization curve corresponds to progressive involvement of the base layer of ribbon into the magnetization and magnetization reversal processes. An analysis of hysteresis loops shows that the field bias is related to the interlayer interaction of the surface and the bulk of the ribbon, whereas the formation of asymmetric hysteresis loops occurs with the participation of the second layer with gradual implementation of it into the magnetization and magnetization reversal processes.

钴基非晶合金带在淬火状态下的磁化过程的特殊性

摘要--对不同制造商生产的软磁 Co 基非晶合金 AMAG-172（Co-Ni-Fe-Cr-Mn-Si-B）的研究表明，在淬火状态下，PC MSTATOR（Borovichi）生产的磁带宽度上的磁特性不均匀性大大降低。然而，整个磁带厚度上的不均匀性会发生，这有利于形成磁导率的双峰场依赖性。根据磁导率第一个最大值范围内磁化曲线初始部分的阶梯形状和弱磁场中磁化过程的间歇性，我们可以得出结论：在 PC MSTATOR 中生产的磁带的磁场依赖性第一个最大值的形成与表层的独立磁化反转有关。磁带的基底层参与了第二个最大值的形成。在 JSC NIIMET 制造的样品中，磁化曲线初始部分阶梯状的平滑形状与带状基底层逐渐参与磁化和磁化反转过程相对应。对磁滞回线的分析表明，磁场偏差与表面和色带主体的层间相互作用有关，而非对称磁滞回线的形成则与第二层逐渐参与磁化和磁化反转过程有关。

期刊介绍： The Physics of Metals and Metallography (Fizika metallov i metallovedenie) was founded in 1955 by the USSR Academy of Sciences. Its scientific profile involves the theory of metals and metal alloys, their electrical and magnetic properties, as well as their structure, phase transformations, and principal mechanical properties. The journal also publishes scientific reviews and papers written by experts involved in fundamental, application, and technological studies. The annual volume of publications amounts to some 250 papers submitted from 100 leading national scientific institutions.
