ABSTRACT
The most widely used magnetic devices in the low frequency regime are power transformers and electric motors. The relationship between microstructure such as grain orientations and magnetic properties of silicon steel has been well established. Possible use of metallic glasses of magnetic applications was realized with the synthesis of a noncrystalline Fe80B20alloy in ribbon form by a rapid quenching technique. In addition to the magnetization processes the behaviors of magnetic domains during excitation determine the performances of magnetic materials. One of the dominant contributions to the bulk magnetic anisotropy resulting in a magnetically easy axis of a crystalline ferromagnet is the magnetocrystalline anisotropy which arises from magnetic interactions between atoms situated at certain lattice sites. Although phosphorus tends to ease the glass formability of iron-base alloys, it also reduces the thermal stability of the alloys.
