Description
The crystal structure, ferromagnetic properties, and thickness of grain boundaries separating the grains of a Nd2Fe14B-type permanent magnet significantly influence the figures of merit such as coercivity, remanence or the energy density product BHmax. Grain boundaries act as anisotropy defects. We use micromagnetic simulations to quantify the influence of those on coercivity/knee field.
