Abstract—The effect of magnetically dependent absorption of radio-frequency high-frequency radiation detected by the method of optically detected magnetic resonance has been studied, and an explanation for it is proposed. A method of high-frequency excitation of optically detected magnetic resonance in nitrogenvacancy color centers in a diamond crystal has been experimentally studied that provides magnetometric sensitivity at the level of units of nanoteslas in the 1-Hz band in zero and weak (
