Micromagnetic study on the effect of circularity in hot-deformed Nd-Fe-B magnets [PDF]

open access: yesAIP Advances
In general, the grain size in micromagnetic modeling for hot-deformed magnets is determined by the size of the c-plane and the aspect ratio, which cannot reflect the randomness of the grain shape. In this study, we consider, from a micromagnetic point of
