磁性材料的许多重要磁性参数如矫顽力、磁导率、剩磁比和损耗以及整个磁化过程,都与磁畴结构及其在外磁场下的运动变化密切相关.为了应用和研究具有优良高频磁性能的非品合金FeNi_(38)Mo_4B_(18)的磁结构,本文用粉纹法研究了该台金的磁畴结构、外磁场和消除应力退火对磁畴结构的影响及合金的表面形状对磁畴的影响,并对所得结果进行了分析讨论.
Many important magnetic parameters of magnetic materials, such as coercivity, permeability, remanence and loss, and the entire magnetization process, are closely related to the magnetic domain structure and its movement in the external magnetic field.In order to apply and study the high frequency Magnetic properties of the non-alloyed FeNi_ (38) Mo_4B_ (18) magnetic structure, this paper by the grain pattern study of the gold domain structure, the external magnetic field and stress relief annealing of the magnetic domain structure and the alloy surface shape On the impact of the magnetic domain, and the results were analyzed and discussed.
