Abstract

Possible acoustic self-induced transparency of magneto-ordered medium is under investigation in the paper. Heisenberg model of a ferromagnet and antiferromagnet in magnetic field is considered as an example. The allowance made for exchange interaction between electron spins is shown to result in qualitative change of self-induced transparency picture; in particular, the dispersion low for the carrier sound wave varies along with the character of phase modulation and the shape of the stationary pulse. The possibility of experimental observation of the above-mentioned phenomenon is discussed.
