Abstract
The method of exciting a soliton and complicated nonlinear structures in easy axis (EA) magnets based on the autoresonance effect upon pumping by an external circularly polarized field with a slowly varying amplitude is proposed. The threshold conditions of the pumping field amplitude ensuring such an excitation are determined. It is shown that autoresonance can also be used to control the parameters of soliton spin waves, in particular, their velocity and amplitude. The conditions of capturing a soliton by external pumping are found. The equations describing the time evolution of soliton parameters under the action of an external ac fields are obtained. It is discovered that a soliton can also be controlled with the help of the scattering-at-resonance effect.
