Abstract:
This paper presents the results of theoretical and experimental investigations of the domain wall pinning in a planar ferromagnetic system consisting of a nanowire and four rectangular uniformly magnetized nanoparticles located at an angle to the nanowire axis. Based on the calculations of the interaction energy of the domain wall with stray fields of nanoparticles and the micromagnetic simulation, it has been demonstrated that, in this system, there are different variants of the domain wall pinning, which are determined by the relative orientation of the magnetic moments of nanoparticles and the magnetization of the nanowire. The possibility of the creation of magnetic logic cells based on the structures under consideration has been discussed.
