Abstract

Structure and dynamics of two interacting 180° domain walls of different polarity, which form a 360° wall, have been investigated analytically and numerically in a uniaxial ferromagnet with a large quality factor placed in a magnetic field. A strong influence of damping and field on the frequency and nature of the dynamic transformation of the structure of interacting domain walls from the Bloch to the Néel type and vice versa has been revealed.
