Domenii publicaţii > Fizica + Tipuri publicaţii > Articol în volumul unei conferinţe

Editorial: IEEE Transactions on Magnetics, 37/4, p.2061, 2001.

Rezumat:

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, 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.
