Abstract
The possible magnetization configurations of individual circular Co(0001) d ots 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 2 5 nm where a transition into a weak stripe structure occurs.
