Fig. 3: Comparison between band structure of ScV₆Sn₆ and TbV₆Sn₆.

a Fermi surface map of ScV₆Sn₆ overlaid with the 2D BZ. b, c Dispersions acquired along the high-symmetry direction Γ-K-M, with the polarization LH and LV + \(\odot\), respectively. Here LH and LV are defined as the in-plane component along the horizontal and vertical directions of the image. When there is an out-of-plane contribution due to experimental setup, we denote it by +⊙. The red dashed line serves as a guide to the eye for the band forming the VHS near E_F. d Band structure of ScV₆Sn₆ in the pristine phase calculated by DFT. e–h Data (83 eV photon energy) and DFT calculations of TbV₆Sn₆ corresponding to each panel of ScV₆Sn₆ above.
