The amorphous state is characterized by metastability, which results in structural relaxation even at low temperatures. These relaxations contribute to the magnetic properties of amorphous alloys, such as the value of the coercive field, losses from hysteresis or magnetic susceptibility. In amorphous materials, as opposed to crystalline ones, the description of relaxation phenomena is difficult due to the fact that these processes are described by the activation energy spectrum and occur in a wide temperature range. The paper presents the results of the analysis of migration processes based on the adopted H. Kronmüller model, in which the reorientation of atoms takes place in areas of reduced volume called free volumes.
