A (Nd, Zr)(Fe, Co)11.5Ti0.5Nx compound as a permanent magnet material

Abstract

We studied NdFe11TiNx compounds as permanent magnet materials. The (Nd0.7, Zr0.3)(Fe0.75Co0.25)11.5Ti0.5N0.52 powder that contained a limited amount of the α-(Fe, Co) phase shows fairly good magnetic properties, such as a saturation polarization (Js) of 1.68 T and an anisotropic field (Ha) of 2.88 (Law of approach to saturation) -4.0 MA/m (Intersection of magnetization curves). Both properties are comparable to those of the Nd2Fe14B phase.
