The features of current instabilities in Mn4Si7–Si:Mn–Mn4Si7 and Mn4Si7–Si:Mn–M heterojunctions are investigated at low temperatures and upon “intrinsic” illumination with hv > 1.12 eV. It is shown that low-frequency self-oscillations related to intensification and quenching of the photoconductivity can be obtained at high applied voltages.
