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