Description
The dependence of the magnetic viscosity on texture can be used to study a model recently proposed by Givord and co-workers to describe the angular dependence of the coercive field in NdFeB magnets. We have measured the magnetic viscosity parameter S/sub v/ for samples of Magnequench (MQ) II and III as a function of magnetic field H and temperature T above room temperature. Near room temperature, S/sub v/ for MQ II is smaller than for MQ III, while for temperatures above ∼70 0C, the opposite behavior is observed. This temperature dependence is discussed and compared with that observed in sintered NdFeB and NdDyFeB magnets
