摘要：

The origins of gyroremanent magnetization (GRM) in single domain particles are studied using a dynamic model based on the Landau-Lifschitz equation. The results show an asymmetry in the motion of the magnetic moment of a particle with three unequal axes of anisotropy. This asymmetry is interpreted in terms of an effective bias field which gives a good qualitative explanation of the origins of GRM.
