Abstract
In order to develop high coercivity Dy-free Nd-Fe-B based permanent magnets, it is necessary to design the optimum microstructure that result in a high coercivity. In this work, we employed micromagnetic simulation to study the influence of grain morphology to the coercivity of Nd-Fe-B based permanent magnets with different grain boundary composition.
