Outline of Final Research Achievements

The electronic structure, magnetic properties and the growth mechanism of single-atomic layer of MnN and CrN self-assembled nano-islnads on Cu(001) substrate have been investigated. MnN has been revealed to have a magnetic moment and show antiferro- or para-magnetism. Its electronic structure has significant anisotropy due to reduced dimensionality in a single-atomic height of the film. The growth mechanism of CrN nano-islands has been revealed to be very similar to that of MnN. Two kinds of CrN nano-islands were observed to grow on Cu(001) substrate.
