  We represent the results of micromagnetic modeling and experimental magnetic
force microscopy investigations of domain wall (DW) pinning-depinning effects
in the hybrid systems consisting of ferromagnetic nanowire (NW) and two
ferromagnetic nanoparticles (NPs). It was demonstrated that the special NW-NPs
configuration including the NW with DW nucleating bulb at one end and two-NP
gate enables the realization of controlled DW pinning-depinning based on
switching of magnetization in NPs subsystem. The algorithm of external driving
field manipulation and independent NPs switching, which allow one to develop a
new type of magnetic logic cells, is proposed.
