Abstract: Using the methods of micromagnetic modeling, the dependence of the structure and energy of a domain wall localized in the magnetic bridge between ferromagnetic films on the geometric parameters of the system has been investigated. The effect of displacement and change in the shape of the magnetization curve of the soft magnetic layer caused by the exchange interaction with the magnetic hard layer through a magnetic filament has been demonstrated.

Keywords: exchange interaction, magnetic filament, domain wall, micromagnetic modeling.
