| Abstract: | Coupling of electron spin to optic phonons due to spin—orbit interaction is studied theoretically for small-gap semiconductors in the presence of a magnetic field. We predict an anomalous behaviour of magnetic levels when spin-flip energies become equal to the phonon energy. The effects should be observable in HgTe-type materials. |
