Research on Magnetic Anisotropy in Amorphous Materials with Soft Magnetic Properties

Abstract

During the magnetization process, the increase in magnetization is blocked by the increase in the magnetic field strength. The reason for these magnetic delays may be the magnetic anisotropy of the tested material. In crystalline materials, this phenomenon is quite well described and is related to the parameters of the crystal lattice. For amorphous alloys, which do not have long-range atomic order, this phenomenon has been much less studied. The paper presents the results of studies on the primary magnetization curves for two different alloys showing soft magnetic properties measured in three different directions: parallel to the casting direction, perpendicular to this direction, and perpendicular to the alloy surface. As indicated by the research, in amorphous materials, one can distinguish the direction of difficult magnetization and two easier ones, which means that the phenomenon of magnetic anisotropy occurs in them.
