Popis: Magnetoelastic interaction near a spin reorientation transition leads to giant elastic anharmonicity and magnetic field sensitivity of acoustic parameters of magnets. Collective oscillations are excited and analyzed for the system of parametric quasi-sound vibrations of a hematite (α-Fe 2 O 3 ) single crystal. Bistability of collective oscillations is observed and studied.
