Spontaneous current oscillations were observed in n‐type germanium containing manganese. The latter was compensated with antimony so that the upper level E c −0.37 eV was only partly filled with electrons. The spontaneous current oscillations were observed at room temperature or near it, and for an electric field strength of several tenths of V/cm. The oscillation frequency was in the range of 0.1 to 1 MHz. The relative amplitude of the current oscillations reached 50 to 90%. As was shown by the probe measurements, the instability was a bulk phenomenon and contact effects were not essential. It was proved that this phenomenon might be interpreted in terms of excitation of the recombination waves predicted in [1].
