Magnetic film for a magnetic device, magnetic head for a hard disk drive, and solid-state device

摘要

There is provided a magnetic material with a high saturation magnetization of 2.46 Teslas or above. By using this magnetic material in a recording head, it is possible to record information with a higher density on a recording medium. The magnetic material can also be applied to various kinds of solid-state devices. A magnetic film for a magnetic device (10) is composed of a multilayer film where ferromagnetic films and palladium films (12) or alloy films including palladium are alternately laminated. The laminated palladium films (12) or alloy films including palladium have a main crystal structure that is a body-centered cubic structure, and the multilayer film is formed by dry processing.
