PROBLEM TO BE SOLVED: To provide a method for producing a high frequency magnetic material having excellent magnetic properties, excellent thermal stability and high yield in a high frequency band. SOLUTION: A salt containing a magnetic metal element, a salt containing a metal element that forms an oxide phase and an added oxide phase are alkoxide, hydroxide salt, sulfate salt, nitrate salt, carbonate salt, carboxylate salt, The difference between the standard formation energy of the magnetic metal particles and the standard generation energy of the insulating oxide is 100 kJ / mol or less in the temperature range of 100 to 800 ° C. A precursor which is a certain system is reduced and synthesized. [Selection figure] None |
