Investigation of Magnetic Structure of MnTe/CdTe Multilayers by Neutron Diffraction

Abstract

ABSTRACTNeutron-diffraction studies of MnTe/CdTe superlattices with very thin CdTe spacers are reported. Results indicate the formation of spin helices (consistent with the tensile nature of strain in the MnTe layers) and coherence between the helices in different MnTe layers. Possible mechanisms for the interlayer correlations are discussed.
