Figure 5. The ground state phase diagram in absence of demagnetisation energy contribution.

Figure 5

The scalar value Inline graphic as a function of disk sample diameter Inline graphic and external magnetic field Inline graphic computed for the ground state at every phase space point in absence of demagnetisation energy contribution for (a) a 3d mesh and (c) for a 2d mesh. In order to better resolve the boundaries of the Helical (H) state region, the skyrmion number Inline graphic is shown in (b,d). (e) The magnetisation configurations of three identified ground states as well as the out-of-plane magnetisation component Inline graphic along the horizontal symmetry line.
