Interlayer correlations in ferromagnetic semiconductor superlattices EuS/PbS

Neutron diffraction and reflectivity data from all-semiconductor ferromagnetic/diamagnetic superlattices EuS/PbS provide direct evidence of antiferromagnetic coupling between EuTe layers across up to 90 A ̊ of diamagnetic PbS, despite the absence of mobile carriers that can support long-range RKKY i...

Description
Summary:Neutron diffraction and reflectivity data from all-semiconductor ferromagnetic/diamagnetic superlattices EuS/PbS provide direct evidence of antiferromagnetic coupling between EuTe layers across up to 90 A ̊ of diamagnetic PbS, despite the absence of mobile carriers that can support long-range RKKY interactions.
