Abstract:
Static and dynamic properties of domain walls in magnetic multilayers are theoretically studied. The case of wall perpendicular to the magnetic layers plane are considered. It is found eight exact static solutions corresponding to the various types of domain walls in multilayers. Some of them have no analogue in usual magnet. The nonlinear equations of the dynamics of the magnetization for the antiferromagnetic exchange interaction between magnetic layers are derived. The domain wall dynamics is studied in two different approximations: a strong exchange approximation and a strong demagnetization energy.
