Antiferromagnetic Interlayer Coupling in Ferromagnetic Semiconductor EuS/PbS(001) Superlattices
Antiferromagnetic coupling between ferromagnetic layers has been observed for the first time in all-semiconductor superlattice structure EuS/PbS(001), by neutron scattering and magnetization measurements. Spin-dependent superlattice band structure effects are invoked to explain the possible origin and the strength of the observed coupling.
