a PL spectra at ±0.4 T (top), ±0.2 T (middle) and ±0 T (bottom), respectively. The insets are the corresponding PL microscopic images. Scale bar, 2 μm. b Symmetry analysis of the lattice structure and the FM (top), Mixed (middle), and AFM (bottom) structures of 3L CrSBr. The spatial-inversion operation is denoted by the symbol i. The CrSBr layer with charge transfer from the contacted graphene is marked by the green arrows. The charge transfer breaks the inversion symmetry of the lattice and FM, Mixed, and AFM states under the spatial-inversion operation i. c Temperature dependence of SHG intensity for the two AFM states. The red and black solid curves are shown as a guide for the eye. d SHG excitation spectra at ±0.4 T (top), ±0.2 T (middle), and ±0 T (bottom), respectively.
