Abstract

The authors investigated the transverse magnetic stress (TMS) of rapidly quenched NdFeB by measuring the θ-remanence for 0<θ⩽180°, where θ is the angle between the direction of the applied field during the measurement and the direction of the previous magnetization. Through TMS the remanence was spread out over a wide field range, H≈0 to H>2750 kA/m. This result can be explained by interaction fields, where positive and negative interaction fields of more than 1000 kA/m must be assumed. It is suggested that the discrepancy between the 180° remanence and the 90° remanence is due to the magnetic hardness of the grains, which depends on the projection of the magnetizing field on the easy axis of the grain
