Abstract:
The energy of perfectly oriented thick ferromagnetic films at different applied
magnetic field and stress was studied using classical model of Heisenberg
Hamiltonian. For the values of parameters used in this report, the energy required to
orient the film with 1000 layers in 41.4° or 57.6° directions becomes minimum at
applied magnetic fields of
ω
Hout = 4.8 or
ω
Hin = 4.8, respectively. The film can be
easily oriented in 172° direction by applying the external stress
ω
Ks = 3.6
perpendicular to the film plane, for the values of parameters used in this report. These
final results mainly depend on the values of other parameters used for calculations. The
energy becomes minimum and maximum at almost the same values of oriented angle
(θ), in plane magnetic field, out of plane magnetic field and stress for both sc(001) and
bcc(001 lattice types. But the values of energies corresponding to maxima and minima
are slightly different for the sc(001) and bcc(001) lattices.
