Interlayer Coupling and Quantum Size Effects in Superlattices

In this report authors place their focus on Interlayer coupling, specially regarding magnetic metal/rare earth systems' coupling they introduce the vibration phenomena with governing theoretical calculations that match experimental results. Interlayer coupling in effect is known to be as a result of through electron wave's quantum interference based on quantum size effect. Next they introduce Interlayer coupling for which they use non metallic, non magnetic spacer followed by an example of magnetic/semiconductor artificial lattice. KR's Cu film thickness dependency is shown for Co/Cu and Co sub 9 Fe/Cu artificial lattice. Within artificial lattice the symmetric translation is maintained, the interaction based on RKKY does vibrate at 1/2k sub f period, which occurs when scattering of conduction electron is considered to be of first dimension, and approximated as free electron. In metals however conduction electron has a Fermi energy as the scattering vector shows, which along the film thickness it is no longer a spanning vector. Regarding vibration due to gaps and their changes, when quantum interference of conduction electron is taken into account, it is expected that exchange joint vibration of intermagnetic layers do vary as well. This paper proceeds with covering magnetic and anti-magnetic vibration regarding Interlayer Fe with introduced amorphous (a-)Si.
