  • Magneto-crystalline anisotropy calculation in thin films with defects

    Creator:
    Matusevich, David Sergio
    Abstract:
    The code is developed for the calculation of the magneto-crystalline anisotropy (MAE) in thin films using a classical Heisenberg hamiltonian with a correction developed by Van Vleck. A Metropolis style Monte Carlo algorithm was used with adequate corrections to accelerate the calculation. The MAE was calculated for the case of...

  • Calculation of magnetocrystalline anisotropy

    Creator:
    Schneider, Gunter
    Abstract:
    The magnetocrystalline anisotropy energy (MAE) for fcc Ni and bcc Fe is calculated as the difference of single particle energy eigenvalue sums using a tight-binding model. For nickel we predict a MAE of -0.15 eV and the wrong easy axis, for iron we find a MAE of -0.7 eV with...

  • A theoretical description of anisotropic chemical association and its application to hydrogen-bonded fluids

    Creator:
    Peery, Travis B.
    Abstract:
    The thermodynamic and structural effects of highly anisotropic, short-ranged attraction are investigated for single- and four-site interaction models using Wertheim's multi-density graph theory of chemical association. Both models consist of associating hard spheres, where the saturable attraction sites are described by conical wells centered in the hard core and evaluated...
