Structural and Magnetic Properties of Some RE-(Fe,Mn)-(B,X) Alloys

  • W. Rodewald


The effect of a partial substitution of Fe by Mn on the magnetic properties of sintered Nd-Fe-B magnets has been exa mined. The intrinsic magnetic properties of RE modified Heus ler alloys, RE: Nd, Sm, Dy and of Mn-rich compounds of different RE-Mn-X systems, X: B, C, were investigated.

Additions Nb or Mo to Nd2(Fe,Co)14B result in precipitation of hexagonal NbFeB or tetragonal Mo2FeB2 compounds. The coercivity of such magnets is still determined by nucleation of reversed domains.
