Nonlinear excitations in quasi-two-dimensional system of spins localized in a Bloch wall
Gornakov V. S. , Dedukh L. M. , NikitenkoV. I.
Solitary nonlinear soliton-type waves have been observed in a system of spins localized in a monopolar 180-degree Bloch wall of yttrium ferrogarnet. These waves arise under the influence of a sinusoidal magnetic field acting along the magnetization vectors in neighboring domains.
