  • Abstract
    The self-focussing of sound beams related with the special type of acoustic dispersion in some antiferromagnets possesing a "soft" magnetic mode is theoretically examined. The considerable acoustic nonlinearity of antiferromagnets is expected to facilitate the experimental observation of the self-focussing effect. Ultrasound ( \\sim10^{2} MHz) strains as small as \\sim10^{-6} are sufficient for experiment with α-Fe2O3or TmFeO3.
