Abstract
A magnetic film comprises a platinum layer having a (001) plane orientation and an island-shaped iron-platinum crystalline arranged on the platinum layer and having a (001) plane orientation parallel to the (001) plane orientation of the platinum layer, wherein the island-shaped iron-platinum crystalline has a composition region consisting of 50 atomic % of each of iron and platinum and exhibits a perpendicular magnetic anisotropy having a high coercive force in a direction perpendicular to the surface of the platinum layer.
