Magnetoplasma lamination due to microwave gyroresonant heating

The hysteresis transitions between two temperature states of a collisional magnetoplasma due to Joule heating near the electron gyroresonance are analysed. The propagation of intense extraordinary gyroresonant microwave across the magnetic field in a plasma is responsible for such jump-like thermic effects, the wave amplitudes being less than the 'characteristic plasma field'. The transversal heat conductivity may lead to the formation of spatially periodical temperature profiles in the hysteresis region of wave's intensity; the spatial periods of such profiles are much less than the Joule dissipation length of heating wave. The thermodiffusion, stimulated by temperature lamination, may form the spatial oscillations of magneto-plasma density across the magnetic field.
