Abstract
Recent work of the author (abstr. A64846 of 1972) on the acoustic attenuation due to the spin-phonon interaction in a concentrated paramagnetic crystal with spin 1/2 is applied to the geometry of interest for an acoustic-wave rotation experiment. It is shown that the intrinsic linewidth due to the spin-phonon interaction should not prevent observation of acoustic-wave rotation. A region of the coupled mode spectrum exists where the attenuation due to the intrinsic linewidth is negligible but yet the angle of rotation should be measurable even in the case of paramagnetic ions only weakly coupled to the lattice.Keywords
