Domain Wall Nucleation in Ferromagnetic Nanowire With Perpendicular Magnetization Stimulated by Stray Field of V-Shaped Magnetic Particle

We report the results of micromagnetic simulations of domain wall nucleation and pinning/depinning processes in ferromagnetic planar structure consisting of nanowire (NW) with perpendicular anisotropy and special V-shaped nanoparticle with in-plane anisotropy located on the top of NW. The magnetizat...

Description
Summary:We report the results of micromagnetic simulations of domain wall nucleation and pinning/depinning processes in ferromagnetic planar structure consisting of nanowire (NW) with perpendicular anisotropy and special V-shaped nanoparticle with in-plane anisotropy located on the top of NW. The magnetization reversal features of this system in an external magnetic field are investigated depending on the direction of the particle magnetic moment. Possible variants of magnetic logic cells based on such system are discussed.
