ABSTRACT
The occurrence of ferromagnetism in the metallic phase of (Ga,Mn)N thin layers is studied by Monte Carlo simulation assuming an indirect exchange of the Ruderman–Kittel–Kasuya–Yosida type, via the spin-polarized hole system. We take into account a possible polarization of the hole gas due to the existence of an average magnetization in the magnetic layer. Transition temperatures one order of magnitude higher than in similar (Ga,Mn)As nanostructures are obtained. Two regimes are observed for the dependence of the magnetization on temperature. © 2004 American Institute of Physics.

    Optical and dc resistivity measurements as well as x-ray spectroscopies have been performed on (Ga,Mn)N films containing Mn at up to 11 at. %. The results indicate that at higher Mn contents, the Fermi level is situated within extended states, while GaN host interband optical transitions are...

    Growth of gallium nitride on GaN(0001) surface is modeled by Monte Carlo method. Simulated growth is conducted in N-rich conditions, hence it is controlled by Ga atoms surface diffusion. It is shown that dominating four-body interactions of Ga atoms can cause step flow anisotropy. Kinetic Monte...

    We have investigated the magnetic properties of (Ga,Mn)As thin films with Mn concentration between 1 and 9%. Ferromagnetic transition temperatures TC of up to 173K are observed. The results are compared to the predictions of the Zener mean-field theory. We find no evidence of a fundamental limit...
