Structure and stability of nonlinear excitations in magnets in the presence of a local rf field and dissipation

Solitonlike excitations localized around a point of pumping of an easy-axis ferromagnet by a circular rf magnetic field are investigated in the framework of the one-dimensional nonlinear Schrödinger equation and its discrete analog. The influence of damping on the character of the localized excitati...

Description
Summary:Solitonlike excitations localized around a point of pumping of an easy-axis ferromagnet by a circular rf magnetic field are investigated in the framework of the one-dimensional nonlinear Schrödinger equation and its discrete analog. The influence of damping on the character of the localized excitations and the stability of various types of such states are analyzed in a simplified piecewise-nonlinear model.
