The calculated DW was compared with the DW estimated by an exact solution for an infinite-length nanowire and a linearly approximated DW. The DW width for the quadratic approximation was approximately equal to the square root of twice the DW width for the linear approximation. The DW energy for the quadratic approximation was less than that for the linear approximation and nearly equal to that for the exact solution., This study was supported by the Japan Society for the Promotion of Science KAKENHI (Grant Number 20H02607)}, pages = {17--21}, title = {WIDTH OF A DOMAIN WALL USING A QUADRATIC APPROXIMATION OF MAGNETIC MOMENTS}, volume = {65}, year = {2023} }
