Fig. 3: Finite-temperature behaviors of the Kondo lattice model.
a,b Temperature dependences of the scalar chirality, \({\chi }_{0}^{2}\) and \({\chi }_{2{{{{{{{{\bf{Q}}}}}}}}}_{\nu }}^{2}\) at zero magnetic field H = 0 (a) and H = 0.004 (b). The dashed (dash-dotted) line represents the transition temperature T1 (T2) in a and \({T}_{1}^{\prime}\) (\({T}_{2}^{\prime}\)) in b. c–e Real-space spin configurations in the SkX2 at T = 0 and H = 0 (c), the TVX at T = 0.006 and H = 0 (d), and the SkX1 at T = 0 and H = 0.004 (e). The color scale indicates \({S}_{i}^{z}\), while the arrows indicate \(({S}_{i}^{x},{S}_{i}^{y})\). The insets display the Fermi surfaces in each state; the sixfold rotational symmetry is broken in all the three states. See the main text.
