TL;DR
This paper investigates how magnetoelastic interactions stabilize long-range magnetic order in two-dimensional ferromagnets, revealing modifications in magnon spectra and finite Curie temperatures.
Contribution
It introduces the role of magnetoelastic exchange in stabilizing long-range order and modifies magnon spectra in 2D ferromagnets.
Findings
Magnetoelastic exchange leads to a magnon root dispersion law.
Magnetoelastic interactions create a gap in the excitation spectra.
Long-range magnetic order is stabilized with a finite Curie temperature.
Abstract
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.
