Understanding Signatures Of Emergent Magnetism In Topological Insulator/Ferrite Bilayers
What Has Been Achieved:
This paper reported a comprehensive study of magnetic proximity effect (MPE) in bilayers that interface a topological insulator (Bi2Se3) with an insulating ferromagnet {MgAl0.5Fe1.5O4), demonstrating the need for careful interpretation of polarized neutron reflectometry and anomalous effect data that are often used to show purported evidence of MPE.
