(A) Illustrates the atomic and electronic structure of MoSe2/MnSe2 vdW heterostructures. Side view of MoSe2/MnSe2 bilayers under photoexcitation, where purple, magenta and green represent Mo, Mn and Se atoms, respectively. (B) Density of states for Mn and Mo atoms on MnSe2 and MoSe2 layers, with red and black arrows denoting the pathway of photoexcited spin transfer from Mn to Mo atoms. (C) Regular array of truncated-nanocone-shaped Au–TbCo antennas. (D) Peak demagnetization values plotted against applied fluence. The solid data points correspond to measurements along a direction labeled dS+L, while the open data points represent measurements along the perpendicular direction labeled dL. Solid lines indicate Curie-law fits for data points along the dS+L direction, and dashed lines represent Curie-law fits for data points along the dL direction. Red data points and lines indicate on-resonance pumping, while blue data points and lines denote off-resonance pumping of the localized plasmon mode. Adapted with permission from He et al.
