  A Solution of Fourth Order Perturbed Heisenberg Hamiltonian with Seven Magnetic Parameters

  By M.S.M. Farhan, Pubudu Samarasekara

  Abstract: For the first time, the fourth order perturbed Heisenberg Hamiltonian with all seven magnetic energy parameters was solved for simple cubic structured ferromagnetic ultrathin films. Spin exchange interaction, magnetic dipole interaction, second order magnetic anisotropy, fourth order magnetic anisotropy, applied magnetic field, demagnetization energy and stress induced anisotropy were considered. 3D graphs of total magnetic energy versusstressinduced anisotropy and angle were plotted for different values of second order and fourth …
