摘要：

The critical exponents (γSR and γSR) for spin reorientation (SR) phase transitions in hard intermetallics (ErxRE1-x)2 Fe14B have been determined from ac susceptibility (χH) measurements. For Dy series conical (C) and planar phases are observed, and for the Nd ones, two C phases. A model of scaling of χH is developed, taking the magnetization cone angle θ as the order parameter, and a critical exponent, ωSR = γSR - βSR is introduced. © 1990.
