Fig. 3: The detailed band structure of the valence bands without SOC.
From: Symmetry and minimal Hamiltonian of nonsymmorphic collinear antiferromagnet MnTe
a, b The band structures with Te(5p) orbital component near a the Γ point and b the A point, respectively. The k-point path is shown in c. d Two degenerate states at A point, the symmetrized A–B sublattices with up spin \(\left\vert S\uparrow \right\rangle\) and the anti-symmetrized A–B sublattices with down spin \(\left\vert A\downarrow \right\rangle\). e the band structure in the kxky plane where \(k_{z}=0.45\frac{2\pi }{c}\) (near \(\tilde{A}=(0,0,0.45)\)) in the reciprocal space. Red and blue curves represent spin up and down bands, respectively. f The energy surface for the valence band in kx-ky plane near \(\tilde{A}\) point. The red and blue dots represent the spin up and down, respectively. The units of k-points is Å−1.
