The possible magnetization configurations of individual circular
Co(0001) dots are investigated by means of 3D micromagnetic
simulations as a function of dot dimensions. In zero applied
field, the vortex state corresponds to the ground state for
diameters larger than 60 nm and up to a thickness of 25 nm where a
transition into a weak stripe structure occurs.
