Breathers and envelope solitons at a domain wall in a uniaxial ferromagnet
Popkov A. F.
The MHD equations for a domain wall in a uniaxial ferromagnet are reduced for a study of small-amplitude nonlinear spin-wave excitations localized at the wall. Solutions describing breather waves are found. The conditions under which these waves can exist in a steady state in an alternating magnetic field are found.
