Theoretical and experimental study of Fe/Cr nanometric quasiperiodic multilayers
An experimental and theoretical study of magnetization curves of Fe/Cr nanometric magnetic films grown with the structure of the quasiperiodic Fibonacci sequence is presented. Fe ferromagnetic films with interfilm exchange coupling provided by intervening Cr non-ferromagnetic layers were grown on...

| description |
An experimental and theoretical study of magnetization curves of Fe/Cr nanometric magnetic films grown
with the structure of the quasiperiodic Fibonacci sequence is presented. Fe ferromagnetic films with
interfilm exchange coupling provided by intervening Cr non-ferromagnetic layers were grown on MgO
(100) by dc magnetron sputtering at 300 ◦C. The magnetization curves were investigated using the
magneto-optical Kerr effect with the external field applied along the easy axis. The theoretical approach
for this system is based on a realistic phenomenological model that includes the following contributions to
free magnetic energy: Zeeman, cubic magneto-crystalline anisotropy, as well as bilinear and biquadratic
exchange energies. Our numerical results are in very good agreement with the experimental data |
