### Abstract

We present calculations for the electronic and magnetic properties of surface y 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 spin-polarized 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 technique within the Korringa-Kohn-Rostoker method.
