More Information
Summary:A magnetic thin film head includes a soft magnetic alloy thin film having in a composition expressed by the formula FeXNYOZ, wherein each of X, Y and Z represents an atomic composition ratio, and preferably having four phases including an iron oxide expressed as Fe2O3, iron nitrides expressed as Fe4N and Fe3N respectively, and alpha -Fe. X, Y and Z appearing in the composition formula are preferably in the following relations:0.005</=Y</=0.120.005</=Z</=0.12X+Y+Z=1
