New types of domain walls

Abstract

We have derived an equation of the magnetization trajectory and an equation of the spatial propagation of the magnetization trajectory. Using this system of equations one-dimensional wall structures can easily be found. This approach can also be widely used in studying non-linear problems. A single domain wall in an infinite uniaxial ferromagnet is studied in the framework of this approach. In the limit of a quality factor going to infinity we have obtained analytical solutions which describe new types of one-dimensional domain walls. The walls consist of a central part and two branches.
