摘要：

Photovoltaic oscillations due to interband magneto-optical transitions have been observed on the quaternary open-gap semimagnetic alloys Hg1-x-yCdxMnyTe. In addition to the conventional transitions, phonon-assisted interband excitations have been observed for the first time on a semiconductor. It is argued theoretically that the resonant phonon-assisted interband transitions must originate from the camel-back shaped Landau subbands. Consequently, our observations confirm the existence of such subbands in the inverted right perpendicular8 valence bands of semimagnetic materials. The determined optic phonon energies correspond to the longitudinal HgTe-related mode.
