A germanium oscillator in a pulsed magnetic field

  • Published:
Soviet Physics Journal Aims and scope

Abstract

Experimental data which confirms the presence of hysteresis of the magnetic threshold field of the helical instability of the plasma in a germanium oscillator are presented. It is shown that hysteresis of the threshold magnetic field is due to the inertia of the change in the effective lifetime of the charge carriers in the specimen when the magnetic field is increased and reduced. The dependence of the hysteresis of the threshold magnetic field on the electric field strength, the magnetic field, and the temperature is discussed.
