ABSTRACT:
A ferromagnetic material having a high coercive force and good squareness ratio prepared by mixing an aqueous solution at least containing a salt of a metal capable of forming a ferromagnetic material with a solution of a reducing agent containing at least one of a boron hydride compound or a derivative thereof to perform an oxidation-reduction reaction, wherein the mixing of the solutions is after adjusting the pH of the aqueous solution of the metal salt to about 3.0 or less, and the pH of the reaction mixture at the end of the reaction is adjusted to at least about 3.0 or higher.
