Magnetic breathers and chaotic wave fields for a higher-order (2+1)-dimensional nonlinear Schrodinger-type equation in a Heisenberg ferromagnetic spin chain

Ferromagnetism, whose physical properties include the Giant-Magneto resistance, spin-transfer torque, spin-Hall effect and so on, attracts researchers' interest in the search for the spin polarizers in spin electronics. In this paper, we investigate a higher-order (2 + 1)-dimensional nonlinear Schrodinger-type equation for a Heisenberg ferromagnetic spin chain with the bilinear and biquadratic interaction. Magnetic breathers are derived. Conditions of the transformation from the magnetic breather to the magnetic soliton are obtained. We get the magnetic chaotic wave fields, in which the magnetic breather-like solitons and rogue waves appear. Effects of gamma on the magnetic chaotic wave fields are studied: As gamma increases, mean amplitude of the magnetic waves in the chaotic wave field increases, and amplitude dispersion degree decreases, where gamma represents the lattice parameter.
