Fig. 1: Electronic structure and total Berry curvature of Mn3Si2Te6 in the ferrimagnetic ground state as a function of pressure and spin quantization axis.
From: Origin of pressure-induced anomalies in the nodal-line ferrimagnet Mn3Si2Te6

a, c Show the total Berry curvature Ωx and Ωz (in units of squared Bohr radii \({a}_{0}^{2}\)) and b, d show the electronic band structure with orbital weights on a high-symmetry path through the Brillouin zone for spin quantization axis parallel to the a direction at a pressure of 16 and 23 GPa, respectively. e, f Show cuts of the total Berry curvature Ωz in the kx-ky plane at kz = 0 for the same pressures and the same orientation of spin quantization axis. The colour scale is cut off at a value of ±60. The grey shaded area represents the Fermi surface. g–l Show the electronic structure and total Berry curvature for spin quantization axis parallel to the c direction and all other parameters equal to (a–f).
