Abstract
Recently, the research and development of high-efficiency motors have been carried out due to spread electric vehicles. It is required the property of high coercivity in permanent magnets (i.e., hard magnets). In the hard magnets, the pinning of the propagation of magnetic domain wall (DW) at the grain boundary (GB) is considered as the origin of the coercivity [1]–[3]. In the analytical studies for the DW pinning field $(H_{\mathrm{p}\mathrm{i}\mathrm{n}})$ at the GB, the effect of the damping constant $(\alpha)$ is not taken into account. In this report, we investigate the effect of $\alpha$ on $H_{\mathrm{p}\mathrm{i}\mathrm{n}}$ by using micromagnetic simulations.
