    CONTRIBUTION OF STRESS INDUCED ANISOTROPY AND APPLIED MAGNETIC FIELD TO THE HEISENBERG HAMILTONIAN OF ULTRA-THIN FERROMAGNETIC FILMS WITH SECOND ORDER PERTURBATION
    P. Samarasekara

    The applied magnetic field and stress induced anisotropy dependence of energy of ultra-thin ferromagnetic films has been investigated using Heisenberg Hamiltonian with second order perturbation. All the simulations were carried out for sc(001) film with three (N=3) layers. The energy becomes minimums at certain values of angles, applied magnetic field and stress, by indicating that film can be easily oriented in theses certain directions by applying particular applied magnetic field or stress. For example, when applied magnetic field ( ) perpendicular to film plane is 3.6, the film can be easily oriented along ?????? and ???????directions. When in plane applied magnetic field is =3, energy minimums can be detected at ??1 and ??2.6 radians. When applied stress ( ) is 2.7, film can be easily oriented in ??2.8 direction.
