Fig. 2: Magnetotransport characteristics and charge order with an in-plane unit cell enlargement of \(\sqrt{3}\) × \(\sqrt{3}\) for ScV₆Sn₆.

a The magnetoresistance measured at various temperatures above and below the charge ordering temperature T^* ≃ 80 K. Black solid lines represent fits to the data by means of the following equation: Δρ/ρ_H=0 = α + \(\beta {\left({\mu }_{0}H\right)}^{n}\)b Kohler plot, Δρ/ρ_H=0 vs \({\left({\mu }_{0}H/{\rho }_{H=0}\right)}^{2}\), of the magnetoresistance, plotted from field-sweeps at various temperatures. c STM dI/dV spectroscopic map and corresponding Fourier transform (inset). The red circled marks the \(\sqrt{3}\) × \(\sqrt{3}\) charge order. Data taken at V = 100 meV, I = 0.5 nA, T = 4.5 K, \({V}_{{{{{{{{\rm{mod}}}}}}}}}\) = 10 meV. d Fermi surface obtained by ARPES showing stronger intensities near K points. The inset shows the autocorrelation of the Fermi surface, highlighting the instability with a vector of \(\sqrt{3}\) × \(\sqrt{3}\) as marked by the red circles. This vector corresponds to the scattering between states at K and \({K}^{{\prime} }\) points as marked by the arrow in the main figure. Data taken at 10 K.
