摘要 PURPOSE:To improve the wear resistance and to reduce the output reduction in a high frequency region by laminating plural thin films of an amorphous magnetic alloy with a nonmagnetic intermediate layer having specified Vickers hardness in-between. CONSTITUTION:Plural thin films of an amorphous magnetic alloy are laminated with a nonmagnetic intermediate layer in-between. The Vickers hardness Hv (100g DPH load) of the material forming the intermediate layer is 400-2,000kg/ mm.<2>. The hardness Hv is that measured when the material is in an ordinary bulk state. In case of >2,000kg/mm.<2> hardness Hv, the edge planeness of the thin films positioned on a face to be butted is deteriorated, and the effective gap width is increased during butting to reduce the output in a high frequency region. In case of <400kg/mm.<2> hardness Hv, the wear resistance is deteriorated.
