Technique for measuring the parameters of polarization of an ultrasonic wave

Method for precise measurements of the ellipticity and rotation of the polarization of a transverse ultrasonic wave is presented. It is applicable for investigating the acoustic analogs of the Faraday, Cotton-Mouton, and Kerr effects. The technique consists of measuring amplitude of the voltage on the receiving piezoelectric transducer at a certain magnetic induction B, relative to an initial one using three different positions of the transducer with futher processing the data with the formulars given in the paper.

Theory of acoustic analog of magneto-optic Kerr effect under magnon-phonon resonance

Theory of the acoustic analog of the polar Kerr effect is developed for an inclined incidence of the p-type wave on the interface between isotropic non-magnetic medium and ferromagnetic cubic crystal. Magnetic field dependences of ellipticity and rotation of the polarization plane of the reflected wave under magnon-phonon resonance are analysed in a weak-coupling approximation for interaction of magnetic and elastic subsystems.
