dc.description.abstractThe energy of thick spinel ferrite films have been calculated by means of classical Heisenberg Hamiltonian. In all cases, maximum energy in ferrite thick films is larger than that of ferromagnetic thick films with 2nd order perturbation. The energy required to rotate from easy direction to hard direction is very small near N=90. Also energy of ferrite thick films with 2nd order perturbation is lager than that of oriented ferrite films. The first energy maximum and minimum can be observed at θ=34.40 and 103.20, respectively. Especially the effect of stress induced anisotropy on energy was investigated, and the film can be easily oriented in some certain directions by applying certain stresses
