Abstract

Spin reorientation and magnetocrytalline anisotropy of (Nd1-xDyx)(2)Fe14B (x = 0.25, 0.5, 0.75) have been studied from mangetization curves of magnetically aligned powders. In (Nd1-xDyx)(2)Fe14B, the spin reorientation temperature (T-SR) decreases linearly on increasing Dy-substitution from 135 to 56 K with the ratio of DeltaT(SR) = - 1.11 K/Dy at% in the composition range of 0 less than or equal to x less than or equal to 0.75. The spin reorientation angle at 4.2 K decreases on Dy-substitution from 30.4 degrees at x =0 to 14.7 degrees at x = 0.75. From the investigation of the magnetocrystalline anisotropy at 4.2 K, the disappearance of the spin reorientation for compositions x greater than or similar to 0.85 is expected.
