Abstract

The variation of energy with demagnetization factor will be investigated for sc(001) and bcc(001) ferromagnetic lattices with four layers using classical model of Heisenberg Hamiltonian. According to 3-D plots, the films with four layers can be easily oriented in certain directions under the influence of particular demagnetization factor and angles for both sc(001) and bcc(001) ferromagnetic lattice structures. A flat part can be seen in the middle of 3-D plots in addition to periodic variations. When the demagnetization factor is given by  = 6, sc(001) film with four layers can be easily oriented in 0.6 radians direction for the energy parameter values used in this simulation. Under the influence of demagnetization factor given by = 5.2, thin film of bcc(001) lattice with four layers can be easily oriented along 0.63 radians direction.
