"Magnetic properties of quantum corrals from first-priciples calculations";

Journal of Physics: Condensed Matter,17(2005), S1037 - S1048.

We present calculations for the electronic and magnetic properties of surface

states confined by a circular quantum corral built of magnetic adatoms (Fe)

on a Cu(111) surface. We show the oscillations of charge and magnetization

densities within the corral and the possibility of the appearance of spinpolarized

states. In order to classify the peaks in the calculated density of

states with orbital quantum numbers we analysed the problem in terms of a

simple quantum mechanical circular well model. This model is also used to

estimate the behaviour of the magnetization and energy with respect to the

radius of the circular corral. The first-principles calculations are performed

fully relativistically using the embedding techniquewithin theKorringa-Kohn-

Rostoker method.
