PROBLEM TO BE SOLVED : To provide a magnet material more excellent in magnetic characteristic than a conventional rare earth iron fluorine magnet. SOLUTION : In a magnet material composed of alloys of a binary system of R-Fe (R is a 4f transition element or Y in a formula) where F is positioned at an intrusion position of a crystal lattice and a ternary system of R-Fe-T (R is as above, T is a 3d transition element excluding Fe, is Mo, Nb, or W in a formula [however, when T is W, R is a 4f transition element or Y other than W]), a part of an Fe site is partially replaced by at least one of Al, Si, and Ga.
