摘要：
The self-consistent field method is used to investigate magnon-phonon interactions in a Heisenberg antiferromagnetic with easy plane anisotropy and single-ion magnetostriction. The coefficient of magnon-phonon coupling is calculated in the first approximation relative to the reciprocal interaction radius. The influence of spin waves and longitudinal spin fluctuations on the temperature dependence of phonon frequencies is examined.
