On a regime of the development of oscillations in a spin oscillator

Experimental and theoretical results are presented on the spike regime of the stabilization of oscillations in a spin oscillator which arise in the case of high values of the gain coefficient in the feedback circuit. Attention is given to differences between transient processes in different types of oscillators with inertial nonlinearity: spin oscillators, solid-state lasers, and oscillators with square-law detectors. As an example, results are presented on the spike regime in an optically pumped Hg-199 spin oscillator.
