Spontaneous symmetry breaking and magnon-phonon spectra
Both the rotation and translation symmetry breaking effects due to magnetoelastic coupling are considered. The former are the magnetoelastic magnon energy gap and the sound velocity change for longwave phonons. The second effects are connected with oscillations of a domain wall “dressed” by non-unif...

| Summary: | Both the rotation and translation symmetry breaking effects due to magnetoelastic coupling are considered. The former are the magnetoelastic magnon energy gap and the sound velocity change for longwave phonons. The second effects are connected with oscillations of a domain wall “dressed” by non-uniform magnetostrictive strains. |
