EFFECT OF STRUCTURAL RELAXATIONS WITHIN THE AMORPHOUS STRUCTURE ON THE MAGNETIC PROPERTIES OF AMORPHOUS TAPES FROM FECOB FAMILY

摘要

The paper presents the research results for the Fe78Co2Si9B11 amorphous alloy, and after the process of annealing resulting only in the relaxation of the material. The structure relaxations occurring in the volume of test samples lead to the changes in their magnetic and mechanic properties. Therefore the studies on the effect of the structure defects on the properties of these type of materials are important. Understanding the processes occurring during the magnetizing of amorphous alloys can be helpful in the design of modern functional materials for special purposes. The main purpose of this elaboration was to determine the effect of the amorphous structure defects in the state after solidification and after heat treatment on the changes in the magnetizing process and in such parameters as the saturation magnetization and the coercivity field.
