  Third Order Perturbed Heisenberg Hamiltonian of BCC Ferromagnetic Ultra-Thin Films

  By P. Samarasekara, N. U. S. Yapa

  Abstract: AbstractFor the first time, the solution of third order perturbed classical Heisenberg Hamiltonian equation with all the seven magnetic parameters including stress induced anisotropy and demagnetization factor is presented in this manuscript. Variation of third order perturbed total energy with applied in plane magnetic field, applied out of plane magnetic field, demagnetization factor and spin exchange interaction is described in this manuscript. Several peaks can be observed in each 3-D …
