Magnitoelastic interaction and long-range magnetic ordering in   two-dimesional ferromagnetics
  The influence of magnitoelastic (ME) interaction on the stabilization of long-range magnetic order (LMO) in the two-dimensional easy-plane ferromagnetic is investigated in this work. The account of ME exchange results in the root dispersion law of magnons and appearance of ME gap in the spectra of elementary excitations. Such a behavior of the spectra testifies to the stabilization of LMO and finite Curie's temperature.
