Abstract: A method of producing a soft magnetic material includes spray drying a slurry containing Fe and X to obtain granules having an average particle size in a range of at least 20 ?m but not more than 200 ?m, where X represents at least one element selected from the group consisting of Ti, Mn, Ni, Co, Zr, Hf, V, Nb, Ta, Cr, Mo, W, Cu, Zn, and Si; and heat-treating the granules in a reducing gas at a temperature in a range of at least 800° C. but not higher than 1200° C. to obtain a heat-treated product.

Abstract: A method of producing a coated soft magnetic material, including: a coating procedure including mixing an aqueous solution containing a phosphate compound and a metal oxoacid compound with a soft magnetic material to form a coating containing a metal phosphorus compound on a surface of the soft magnetic material.

Abstract: A method of producing a coated magnetic material, including: a coating procedure including mixing an aqueous solution containing a phosphate compound and a compound of a metallic element or a semimetallic element with a soft magnetic material to form a coating containing phosphate and the metallic element or the semimetallic element on a surface of the soft magnetic material; and a pH adjustment procedure including mixing an aqueous solution containing a phosphate compound and a compound of a metallic element or a semimetallic element with the soft magnetic material on which the coating is formed, and adjusting a pH of a mixture of the aqueous solution and the soft magnetic material on which the coating is formed to form a coating containing phosphate and the metallic element or the semimetallic element on a surface of the soft magnetic material on which the coating is formed.
