## Description

- description: Intrinsic magnetic topological insulators, in which magnetism and topology
    are inherently combined, are excellent systems to realize exotic phenomena such
    as the quantum anomalous Hall effect. However, there are many reports that show
    that the experimental samples are not so ideal and the effect of the unintentional
    disorder in these systems needs to be considered carefully. In this study, we
    investigate the role of misplaced magnetic atoms as well as nonmagnetic elements
    in the intrinsic magnetic topological insulator heterostructures based on MnBi2Se4
    and Bi2Se3. We find that Mn atoms are not only placed at the central layer of
    the MnBi2Se4 septuple layer (SL) but also intermix with Bi (antisite Mn) as well
    as reside in the van der Waals (vdW) gap. Through a detailed comparison between
    the experimental and theoretical x-ray magnetic circular dichroism (XMCD) spectra,
    we find that the antisite Mn is coupled ferromagnetically, whereas the vdW Mn
    couple antiferromagnetically to the Mn in the central atomic plane of the SL.
    Furthermore, we detect a clear XMCD signal in nonmagnetic Se, providing unambiguous
    evidence of its magnetic interaction with Mn.
