SOLITONS IN THE SPIRAL MAGNETIC STRUCTURES AND THE METHODS OF THEIR EXCITING
In the framework of sine-Gordon model, the complete analysis of structure and properties of the solitons in the spiral magnetic structures is given. It is shown, that a pulsating soliton (a breather) is inseparable from its environment: even if its velocity is zero, it can cause an intensive oscillations of the domain walls (kinks) of the structure. It is found, that the motion of the breather is accompanied by deformations of the kink lattice. That can lead to the formation of extended regions which can be treated as the «precursors» and «tails» of the breather. The possibilities of observing and exciting the solitons in the spiral structures of magnets and in multiferroics are discussed.
