Abstract

A trigon structure formed by submonolayer gadolinium deposition onto Au(111) is revealed as a robust growth template for Co nanodot arrays. Scanning Tunneling Microscopy and X‐Ray Magnetic Circular Dichroism measurements evidence that the Co nanoislands behave as independent magnetic entities with an out‐of‐plane easy axis of anisotropy and enhanced magnetic anisotropy values, as compared to other self‐organized Co nanodot superlattices. The large strain induced by the lattice mismatch at the interface between Co and trigons is discussed as the main reason for the increased magnetic anisotropy of the nanoislands.

39. An estimation ofKp= 0.8 meV atom−1is obtained for cylindrical dots of 1500 atoms and 2 AL height where 194 perimeter atoms would be present. For the 4000 atom dot the dot have to be at least 4 AL high and therefore a minimum of 360 perimeter atoms.
