On the dynamics of domain structure in finite samples

The dynamics of a system of domain walls has been considered in finite samples of a rectangular or a trapezoid (wedge) shape. Based on the solution to the set of equations of motion for the system of domain walls, it has been shown that the equilibrium positions and amplitudes of vibrations of domain walls are determined by the magnetostatic field caused by the sample shape. The role of possible physical mechanisms controlling the translational motion of the domain structure is discussed.
