摘要： A composite magnetic head in which a single crystal ferrite is used at the slide contact portion with the magnetic recording medium and a polycrystalline ferrite is used at the portion constituting the back magnetic circuit, is disclosed. An oxide magnetic thin film is formed at the junction interface between the single crystal ferrite and the polycrystalline ferrite for providing a magnetic head free from diffusion at the junction surface and evidencing only a low slide noise level.

摘要： To provide a magnetic powder production method, a magnetic sheet production method, and an antenna module production method that are capable of reducing a size of magnetic particles, achieving thinning and a low loss, and improving magnetic permeability without lowering it. At least two oxide-based magnetic materials are mixed, preliminarily calcined, and pulverized. The pulverized magnetic materials are typically formed into a paste by being dispersed in an organic solvent, and the magnetic materials are applied onto a film after being subjected to defoaming processing. Accordingly, a sheet-like magnetic material is formed. The sheet-like magnetic material is cut into predetermined sizes so as to be fragmented into particles, with the result that magnetic particles are formed.
