Abstract
The far-IR transmission and photoconductivity in the semimagnetic alloys p-Hg1−x MnxTe (x=0.20–0.22) at temperatures 2–7 K were investigated at fixed frequencies of optically pumped molecular lasers in the region 49–311 µm. We report the observation of photoexcitation of acceptors from the ground into excited states under conditions when the direct interaction of the magnetic moments of the manganese ions becomes substantial and results in the formation of a spin-glass phase. It was found that the internal field produced by the spontaneous and external polarizations of the magnetic moments of the Mn2+ ions in the spin-glass temperature range influences the energy spectrum of acceptors in a magnetic field.
