## Description

- description: The anomalous Hall effect due to an intrinsic magnetic ordering combined
    with topological electronic states is at the forefront of recent study in condensed
    matter physics. The seminal compound MnBi2Te4 has fueled an enormous amount of
    interest in the study of various exotic quantum phenomena such as the axion insulator
    state, the Chern insulator state, and the quantum anomalous Hall effect on this
    material as well as its heterostructural cousins (MnBi2Te4 )(Bi2Te3)n. Despite
    the theoretically expected gapped Dirac surface states in these time-reversal
    symmetry broken topological materials, the electronic band structures are variously
    reported with regard to the presence of the band gap in the Dirac cone. Here we
    report on Sb-doped higher-order Mn-Bi-Te magnetic topological materials in our
    combined study of magnetotransport and angle-resolved photoemission spectroscopy.
    We found multiple magnetic ground states in the Sb-doped antiferromagnetic topological
    insulator MnBi4Te7, driven by a delicate balance of magnetic interactions along
    the van der Waals interlayer direction. Additionally, we detected a gradual shift
    of the Fermi level from the conduction band to the valence band, accompanied by
    charge compensation at approximately 33% Sb doping. Interestingly, we observed
    the gapless Dirac states in pristine MnBi4Te7 and the gapped states in Sb-doped
    MnBi4Te7. We explored this unconventional scenario in the light of recent studies
    from various research groups.
