Influence of quantum confinement on magnetic properties of Fe/Mo/Fe and Fe/Ta/Fe thin-film systems
The magnetic properties of Fe/NML/Fe thin-film structures with Mo and Ta non-magnetic layers (NMLs) grown by magnetron sputtering have been studied using magnetooptical techniques. It is established that the saturation field ( H S ) of the samples exhibits oscillations as a function of the NML thick...

Summary: | The magnetic properties of Fe/NML/Fe thin-film structures with Mo and Ta non-magnetic layers (NMLs) grown by magnetron sputtering have been studied using magnetooptical techniques. It is established that the saturation field (
H
S
) of the samples exhibits oscillations as a function of the NML thickness (
t
NML
) and the period of oscillations depends on the thickness of iron layers. This behavior of
H
S
(
t
NML
) is explained by the oscillatory character of exchange coupling between the ferromagnetic layers. |
