  Simple cubic and body centered cubic ferromagnetic lattices with four layers
were studied using 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.
