摘要: A perpendicular magnetization film of iron-chromium alloy having an easy magnetization axis perpendicular to a plane of substrate, and the preparation thereof. The perpendicular magnetization film provides a dominant peak corresponding to a lattice constant of 2.07 to 2.08 .ANG. in X-ray diffraction spectrum, and possesses a large saturation magnetization of more than 100 emu/cm.sup.3. The perpendicular thin film can be prepared by depositing iron and chromium on the substrate under vacuum or an atmosphere of argon gas at a low pressure.
