摘要
Kinetic Monte Carlo simulations are performed to study the influence of external magnetic fields on the growth of magnetic fcc binary alloy nanoclusters with perpendicular magnetic anisotropy. A model of the underlying kinetics is designed to describe the essential structural and magnetic properties of CoPt3-type clusters grown on a weakly interacting substrate through molecular beam epitaxy. The results suggest that perpendicular magnetic anisotropy can be enhanced when the field is applied during growth. For equilibrium bulk systems a significant shift of the onset temperature for L1(2) ordering is found, in agreement with predictions from Landau theory. Stronger field-induced effects can be expected for magnetic fcc alloys undergoing L1(0) ordering.
