Study on Two-Dimensional Magnetostriction Measurement and Building Factor Evaluation of an Amorphous Ribbon

Abstract

In order to improve efficiency of electric equipment, it is necessary to use a high-quality magnetic material and to fully utilize the magnetic properties without deterioration. It is known that the iron loss of the amorphous material is about one-third of that of the grain oriented electrical steel sheet. However, the amorphous material has a large magnetostriction. The magnetic characteristics were usually deteriorated by the compressive stress. Therefore, it is necessary to understand the magnetostriction characteristics of the amorphous material in detail. In this paper, the magnetostriction of amorphous material is clarified.
