Abstract

The relationship between the magnetic properties of a Co-based amorphous ribbon and its heating by a microwave magnetic field (h_f) was investigated by using a 5.8-GHz single-mode applicator. The amorphous ribbon has a magnetic anisotropy in the ribbon plane. Heating efficiency of h_f which was applied in the direction perpendicular to the casting direction was better than that of it applied along the casting direction. The contribution of magnetic loss to the h_f heating was evaluated quantitatively when the h_f was applied to both directions. The contribution of magnetic loss was more than 80% when the microwave h_f was applied perpendicular to the casting direction, and less than 20% when it was applied parallel to the casting direction.
