(a1–a7) Theoretically calculated changes in the dispersion dependencies of bulk states in the \(\bar{K}\! \varGamma \!Z\) direction of the BZ for FM TI \(\textrm{Mn}_{1-x} \textrm{Ge}_x \textrm{Bi}_2 \textrm{Te}_4\) with varying Ge concentration from 0 to 75%. Changes in the contributions of the Te \(p_z\) and Bi \(p_z\) states are shown in red and blue, respectively. (b1–b6) Theoretically calculated dispersion dependencies of the projected bulk states from the \(\varGamma \!Z\) direction to the \(\bar{K}\!\bar{ \varGamma }\!\bar{M}\) directions of the BZ. The profiles of the density of electronic states at the \(\Gamma\)-point are shown by red lines, depending on the concentration of Ge atoms.
