Currrent Status and Further Research Consideration of Interrelation between Microstructure and Magnetic Properties in Rare-Earth Permanent Magnet Materials

本文阐明了永磁材料的微观结构和技术磁性的内涵和意义。根据反磁化过程中反向畴壁形成和运动的具体特点,综述了稀土永磁材料微观结构和技术磁性关系的研究现状,提出了引入数值计算方法进一步研究其结构-性能关系的某些设想。

The definition and the meaning of microstructure and magnetic properties of rare-earth permanent magnet materials are demonstrated. Based on the nucleation behaviour and the propagation behaviour of the reversed domain walls during magnetization reversal, the current status of the interrelatic between microstructure and magnetic properties are briefly reviewed. For a better understanding of (?) interrelation, it is suggested that the numerical simulation method should be applied to study (?) magnetization reversal process.
