摘要： A ferromagnetic powder and process for producing it are disclosed. The process involves providing reducing a nickel-doped or nickel-coated iron compound in a reducing gas to provide a reduced metal powder including nickel in an amount of 3 to 30 atomic % based on the atomic % of iron present in the reduced metal powder, and treating the reduced metal powder with an organic metal powder. The resulting ferromagnetic metal powder has excellent stability with respect to oxidation and has a high saturation magnetization.

摘要： An improved method of making a magnetic recording material comprises providing a ferromagnetic metal thin layer which has uniaxial anisotropy in any direction on a web by means of plating.A plating solution is jetted onto the web through holes in a conveying pipe set in a plating bath. The web is then moved from the vicinity of the conveying pipe by the spouting force of the plating solution, and then conveyed along a helical path about the conveying pipe without contacting the surface of conveying pipe. Plating occurs while applying a magnetic field to the web.
