Influence of Defects in Amorphous Structure on the Change of the Course of the Primary Magnetization Curve

In ferromagnetic crystalline materials, structural defects are well-defined, and many physical phenomena are explained using them. Apart from crystal grains, they play a decisive role in the magnetization process and shape the course of the primary magnetization curve. On the other hand, in amorphous materials, structure defects are very difficult to define, and their direct observation is impossible. The paper presents a method of indirect observation of amorphous structure defects based on the theory of approach to ferromagnetic saturation.
