Arrays of Fe-nanoparticles grown by STM-assited CVD have been placed on top of a narrow stripe of Py. The magnetic coupling between the nanoparticles and the underlying Py film results in distinct negative jumps of the Py magnetoresistance. The switching of the magnetization orientation of individual particles is clearly reflected in the Py magnetoresistance as a consequence of AMR and DWMR, with a homogeneous particle magnetization orientation yielding the highest resistances.
