a The monolayer, bilayer, trilayer, and bulk Fe3GaTe2 structures, in which the Fe-I, Fe-II, Ga, and Te atoms are colored blue, light blue, green, and orange, respectively. b The orbital-projected band structure of monolayer Fe3GaTe2 structure with different d states of Fe is highlighted by different colors. c–f The calculated band-resolved spin-orbit correlation function \({\langle {{{\boldsymbol{L}}}}\cdot {{{\boldsymbol{S}}}}\rangle }_{nk}\) of the monolayer, bilayer, trilayer, and bulk Fe3GaTe2 structures, respectively. The color represents the correlation for each eigenstate, in which red and blue denote strong positive and negative correlations, respectively. Note that the Fermi energy is set to zero for reference.
