Fig. 1: Schematic illustration and physical properties of CrSBr/FGT heterostructures.

a Schematic diagram of CrSBr/FGT heterostructures and the magnetic coupling effect between different spins. b, c M-T curves of CrSBr (b) and FGT (c) bulk crystals, measured in a 0.1 T external field along the out-of-plane. d TEM image of the cross-sectional region of the heterostructure. Scale bar, 50 nm. e Raman spectra of CrSBr flake, FGT flake, and FGT/CrSBr heterostructure. The square symbols represent the Raman signals of FGT, while the diamond symbols stand for the phonon modes of CrSBr. f The optical micrograph and thickness line profile of FGT/CrSBr heterostructures on SiO2/Si substrate. The red and green dashed lines sketch the areas of CrSBr and FGT, respectively. Scale bar, 20 µm. g KPFM topography and work function plots of FGT/CrSBr heterostructures. The red area is pristine CrSBr, and the green dashed line marks the area of FGT. Scale bar, 5 µm.
