Abstract

This paper describes the relations among anisotropic field(Hk), sheet resistance (Rs) and power losses in Co-Pd-B-O nano-granular films with various compositions and discuss the mechanism of the noise suppression effect in the case of magnetic thin films. Results demonstrate suitable nano-granular magnetic thin films useful for a noise suppressor in semi-microwave bands.
