Abstract
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: RFeF; R(Fe,T)F; RFeF; R(Fe,T)F; RFeF; or R(Fe,T)F(0<x≦3, 0<y≦4, 0<z≦1).
