Simulation of magnetization behaviour in nanocrystalline Pr2Fe14B by micromagnetic finite element method
纳米晶永磁Pr2Fe14B微磁学有限元法的模拟计算研究

Magnetization behaviour in the nanocrystalline Pr2Fe14B has been simulated by micromagnetic finite element method. The decrease of anisotropy in an interlayer leads to the drop of coercivity and enhancement of remanence, while the decline of intergrain exchange coupling increases the coercivity and decreases the remanence. The experimental coercivity and remanence may be simultaneously obtained by selecting proper parameters for the interlayer. Unfortunately, it is difficult to simulate the demagnetization curve of the ribbons before many efforts mustbe paid in future.
