a Phonon spectrum. b Electronic band structure without spin-orbit coupling (SOC), with energies referenced to the Fermi level (EF). Spin-up and spin-down states are indicated by blue and red colors, respectively. c Projected density of state (DOS) for Tc1, Tc2, Te and Si atoms. d Electronic band structure with SOC when the magnetization (M) is aligned along the a-axis. e same as (d) but for magnetization is aligned along the c-axis. f Evolution of the band gap of the FiM order as a function of angle \(\theta\) away from the a-axis.
