Summary: - The structural and magnetic properties of interacting transition-metal clusters on noble-metal surfaces are investigated by first-principles calculations. Special attention is paid to quantum electronic-structure effects, particularly in the small-size non-scalable regime. Simple effective cluster-interaction models are derived on the basis of the DFT calculations in order to determine the structural relaxation in the nanostructure. The fundamental magnetic properties of interacting clusters, such as the spin and orbital magnetic moments, possible complex noncollinear magnetic orders, and magnetic anisotropy energy is determined for the optimized geometries.
