SPIN REORIENTATION AND EXCHANGE INTERACTIONS IN (ND, R)2FE14B (R = Y, GD)

Journal of Magnetism and Magnetic Materials

Exchange fields in both (Nd, Y)2Fe14B and (Nd, Gd)2Fe14B series are determined by analyzing spin reorientation. Results calculated for the two systems suggest that the R-R exchange interactions between R ions are comparable with the crystal-field interaction and that their effect might be taken into account for reproducing the spin-reorientation temperature.
