Journal of Physical Studies 4(3), 321–326 (2000) DOI: https://doi.org/10.30970/jps.04.321 THE MICROSCOPIC THEORY OF COUPLED MAGNETOELASTIC WAVES IN TWO-DIMENSIONAL FERROMAGNETS AT ARBITRARY ORIENTATION OF A WAVE VECTOR Yu. Mitsay, Yu. Fridman, D. Spirin V. I. Vernadskii Tavriis'kyi National University, 4 Yaltyns'ka Str., Simferopil, UA-95007, Ukraine

In the paper the spectra of coupled magnetoelastic waves of an isotropic ferromagnet with the account of dipolar interaction are investigated. From the spectra of quasimagnon and quasiphonon excitations it follows that the propagation velocity of quasielastic excitations depends on the direction of a wave vector.
