Abstract

The magnetisation process of amorphous materials is similar to that of crystalline materials and consists of four stages. Each step influences the formation of the primary magnetisation curve. By using measurements in the “easy,” “intermediate” and “difficult” magnetisation directions, the primary magnetisation curves are obtained, on the basis of which the value of effective anisotropy can be determined.
This paper presents the results of tests that were carried out on two amorphous alloys that are based on an Fe matrix. The value of effective anisotropy was related to the spin-wave stiffness parameter.
