PURPOSE:To upgrade coercive force and to make magnetic characteristic isotropic without execution of a diagonal vapor deposition method by forming an underlying layer consisting of Ge or an alloy contg. Ge on one main plane of a non-magnetic base and forming a thin magnetic metallic film thereon. CONSTITUTION:A thin magnetic metallic film 2 consisting of any one matel among Co, Fe and Ni or an alloy thereof is formed on a non-magnetic base 1 and an underlying layer 3 which expands volumetrically when solidifies, more particularly an underlying layer consisting of Ge or an alloy contg. Ge, for example, an alloy of Ge (5.0% volumetric expansion rate when Ge solidifies) and Au or In is deposited by evaporation under said film to 30-300Angstrom thickness. The layer 3 consists of 80-100atom% Ge and the balance Au or In, etc. The film 2 is formed to 50-1,000Angstrom thickness by vapor deposition from the direction roughly perpendicular to for example, the base 1 without execution of diagonal vapor deposition. |
