“…The presence of manganese (Mn) ions in these solid solutions reveals the existence of new properties of semimagnetic semiconductors and creates wide opportunities for the preparation of magnetic field-controlled diodes operating in the 3-5 µ m wavelength of the spectrum based on them [8,9]. Thus, E g grows sharply in the solid solutions formed by the inclusion of Mn ions into the crystal lattice of lead chalcogenides [10]. On the other hand, the energy spectrum of charge carriers in the magnetic field changes unusually.…”

Herein, the effect of γ-quanta on electrophysical and photoelectric properties of p-type Pb 1−x Mn x Se epitaxial films obtained from the molecular cluster on the glass substrate by the method of condensation has been investigated. It has been established that the acceptor-type local levels with the ionization energy of 0.14 eV and 0.175 eV are generated, when p-type Pb 1−x Mn x Se (x = 0.01) epitaxial films are irradiated by γ-quanta at D >10 kGy doses. The increase in the photoconductivity in the low temperature range 80-180K is due to the discharge of 0.14eV level, but the decrease in the rate of change of photocurrent in the high temperature range is due to the role of local level with 0.175 eV energy as a recombination center.
