## Description

- description: The ultrathin structure and efficient spin dynamics of two-dimensional
    (2D) antiferromagnetic (AFM) materials hold promising opportunities for ultrafast
    memory devices, artificial intelligence circuits, and advanced computing technology.
    For example, chromium thiophosphate (CrPS4) is one of the most promising 2D A-type
    AFM materials due to its robust stability in diverse environmental conditions
    and net out-of-plane magnetic moment in each layer, attributed to anisotropy in
    crystal axes (a and b). However, their net-zero magnetic moment poses a challenge
    for detecting the Néel state that is used to encode information. In this study,
    we demonstrate the detection of the Néel vector by detecting the magnetic order
    of the surface layer by employing localized defects in tungsten diselenide (WSe2).
    These defects are ideal candidates for optically active transducers to probe the
    magnetic order due to their narrow line width and high susceptibility to magnetic
    field (B-fields). We observed spin-polarized charge transfer in the heterostructure
    of bulk CrPS4 and single-layer WSe2, indicating type-II band alignment as supported
    by density functional theory (DFT) calculations. In the A-type AFM regime, the
    intensity of both right-handed and left-handed circularly polarized light emanating
    from the sample remains constant as a function of the applied B-field, indicating
    a constant polarized transition behavior. Our results demonstrate an approach
    to optically characterizing the magnetic states of 2D bulk AFM material by using
    both localized and delocalized defect excitons as a probe, highlighting avenues
    for future research and technological applications.
