Abstract
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.
