Antiferromagnetic interlayer coupling in ferromagnetic semiconductor EuS/PbS(001) superlattices

Abstract

Antiferromagnetic coupling between ferromagnetic layers has been observed for\nthe first time in all-semiconductor superlattice structure EuS/PbS(001), by\nneutron scattering and magnetization measurements. Spin-dependent superlattice\nband structure effects are invoked to explain the possible origin and the\nstrength of the observed coupling.\n
