In a skyrmion which is a magnetically topological object, intrinsic material parameters such as exchange energy, magnetic anisotropy, Dzyaloshinskii-Moriya interaction determine the skyrmion size and wall sixth which are fundamental physical quantities. Besides intrinsic material parameters, magnetic field also has contribution. In this paper, we give a numerical result on skyrmion size as well as wall width. Furthermore, these theoretically expected quantities agree well with experimentally observed skyrmion behavior of the existing materials.
