a Cr1.25Te2 Band dispersions acquired along the Γ − K (hν = 60 eV) and A − H (hν = 80 eV) high symmetry directions with linear horizontal (LH) light polarization. b Same set probed with linear vertical (LV) light polarization to uncover the orbital mixing at the Fermi level. c The electron pocket at the Fermi level is well captured by our ab-initio calculations and allowed us to estimate an inner potential of 8 eV. d Fermi surface maps probed with (top) 60 eV and (bottom) 80 eV photon energies, corresponding to the bulk Brillouin zone center (Γ − K − M) and the Brillouin zone boundary (A − H − L), respectively. e Band structure calculations along Γ − K, Γ − M, A − H and A − L high symmetry directions. f Vectorial micro-spin spectroscopy performed at the Γ point (hν = 100 eV) the resulting polarization vector is consistent with the magnetic ground state of our model. g Electronic structure of the Cr1.5Te2 sister compound which displays similar magnetic behavior.
