| Abstract: | Magnetic properties and electronic structure of V clusters supported on a Cu (1 1 1) substrate, have been calculated from a first principles method. We observe in general non-collinear magnetic structures that are the result of antiferromagnetic interactions on a frustrated lattice. The values of the magnetic moments range from ∼0 to 2.7 μB/atom, depending on cluster geometry. |
