Figure 3: Schematic diagram of 3D modelling.
From: Symmetry breaking in the formation of magnetic vortex states in a permalloy nanodisk
(a) The model system is a Permalloy nanodisk with the radius of 500 nm and the thickness of 100 nm divided into a mesh with an element size of 4×4×6.25 nm3. In this model, the DMI is considered to exist only in the outer elements shaded in yellow as shown in side (b) and top (c) view diagrams. The coordinates of the DMI terms on the lateral and top/bottom surfaces given in our 3D model are indicated.
