The behavior of a longitudinal autosolitons created in excited nonequilibrium electron-hole plasma in compensated p-InSb in crossed magnetic and electric fields is studied experimentally. It is shown that, in magnetic fields ranging from 6.7 x 10{sup 2} to 3.2 x 10{sup 4} A/m, a longitudinal autosoliton is in a state of motion with the average velocity 2 x 10{sup 2}-3 x 10{sup 3} cm/s towards the sample periphery, where the temperature is reduced and the autosoliton is unstable, making the process cyclic and giving rise to oscillations of the current in the external circuit of the sample. In this case, the amplitude and frequency of the oscillations (2144-26855 Hz) depend on the magnetic field. With increasing electric and magnetic fields, the instability of the longitudinal autosoliton current takes on synergetic properties.
