Nonlinear properties of quasi-optic open resonator with a layer of Crv solution in heavy alcohol under the conditions of magnetic resonance

A quasi-optic resonator with a paramagnetic plane-parallel layer is considered. Stationary and non-stationary excitations of fields in such open resonator by a plane linearly polarized electromagnetic wave are studied. The dependences of the OR transmission coefficient as a nonlinear function on the magnetic component of the exciting electromagnetic field and time have been calculated assuming that magnetic susceptibility in paramagnetic is connected with the amplitude of a radio-frequency magnetic field as a nonlinear function determined from the Bloch''s equations. Bistability hysteretic phenomena and unstable operating regimes of the structure in question have been found.
