Abstract
The Faraday rotation of europium organic glass (based on polymethyl methacrylate) in megagauss fields is investigated experimentally and theoretically. The experiment was performed using an MK-1 magnetic explosion generator and laser radiation at the wavelength λ=0.85 µm at T=30 K. It is found that the dependence of the rotation angle of the polarization plane on the magnetic field is nonlinear. The theoretical results are compared with the experimental data. The contribution of the orbital angular momentum of europium ions to the Faraday effect is revealed. The conclusion is drawn that the previously found anomalies of the Faraday effect for the laser radiation at the wavelength λ=0.63 µm are brought about by the magnetooptical resonance, which is induced by the ultrastrong field.
