摘要：
A ferromagnetic compound magnet in accordance with the present invention includes a ferromagnetic compound based on a binary alloy containing R—Fe system (R is a 4f transition element or Y) or a ternary allay containing R—Fe-T system (R is a 4f transition element or Y, and T is a 3d transition element except for Fe, or Mo, Nb or W), the ferromagnetic compound being characterized by: atomic percentage of the element R to the element Fe or to the elements Fe and T is 15% or lower; an element F is incorporated into an interstitial position in a crystal lattice of the alloy. The ferromagnetic compound is expressed in a chemical formula of: R2Fe17Fx; R2(Fe,T)17Fx; R3Fe29Fy; R3(Fe,T)29Fy; RFe12Fz; or R(Fe,T)12Fz (0
