Ground-state magnetization configurations of Py nanospheres according to the diameter.
(a) Finite-element sphere model for diameter 2R = 30 nm. (b) Ground-state magnetization configurations of Py nanospheres for different 2R values as indicated: upper, viewed from positive z-direction and sliced across x-y plane; lower, viewed from positive x-direction and sliced across y-z plane. The color represents the x-component of the local magnetizations, mx = Mx/Ms (see the color bar). The arrows inside the sphere of 2R = 150 nm represent the local curling magnetizations. (c) mx profiles along y axis for different diameters. The inset shows the mx profiles versus the normalized distance for each diameter.
