Fig. 4: Electronic characteristics coupled with magnetism.

a DOS of the ML CrTe₂ supported on bilayer graphene, where the magnetic moment of each Cr cation is oriented along with the O_o (the easy axis) and y (secondary easy axis) directions. b DOSs projected on the Te-p_z and p_x/y orbitals in the ML CrTe₂ with Cr magnetic moments along the O_o axis. Characteristic peaks P₁, P₂ and P₃ are marked. c, d Wavefunction norms of the P₁ peak with the Cr magnetic moments along with the O_o (c) and y (d) directions. The isosurface value of the contours is 0.0002 e/Bohr³. Red and green lines indicate the positions of Te cations and the upper boundary of the contours, respectively. e Tunnelling spectra (V_b = −1 V, I_t = 100 pA, V_mod = 14.14 mV_rms) of the same location indicated in the green cross of Fig. 2d obtained with the same micro Cr tip at various magnetic fields. The black curves are fitted to the peaks around −0.5 eV with a Lorentz shape and a polynomial background. There is a conductance shoulder at about 0.1 V, which is also observable with a W tip (Supplementary Fig. S2). f Statistics of the fitted peak energies of (e) against the magnetic field, where the error bars are from the fitting.
