Momentum-resolved spin splitting in Mn-doped trivial CdTe and topological HgTe semiconductors
Momentum-resolved spin splitting in Mn-doped trivial CdTe and topological HgTe semiconductors
Exchange coupling between localized spins and band or topological states accounts for giant magnetotransport and magneto-optical effects as well as determines spin-spin interactions in magnetic insulators and semiconductors. However, even in archetypical dilute magnetic semiconductors such as ${\mathrm{Cd}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}\mathrm{Te}$ and ${\mathrm{Hg}}_{1\ensuremath{-}x}{\mathrm{Mn}}_{x}\mathrm{Te}$ the evolution of this coupling with the wave vector $\mathbit{k}$ …
