Abstract
We study solitons in systems with ferroelectric and ferromagnetic properties (segnetomagnets). Both subsystems have an easy-axis z anisotropy. We investigate the interaction of a zero spin precession frequency ( ω = 0) dynamical magnetic soliton with the ferroelectric domain wall. It is shown that there is a stable bound state between solitons below a threshold of its co-motion velocity. The threshold is a point of bifurcation, when the double-well effective potential of interaction turns into the single-well one. We calculate the frequency of small relative oscillations of solitons.
