Abstract	We have tested ability of superparamagnetic nanoparticles embedded in matrix to be detected by the magnetic force microscopy (MFM). The sample was characterized by X-ray diffraction and by further magnetic studies such as the temperature and field dependence of magnetization (M) that served as the starting point for an optimal setup for the MFM imaging. To demonstrate the magnetic origin of the phase contrast, the images were taken both with the magnetic and non-magnetic probes. Because of the strong inter-particle interactions arising from the small distances among the particles, only the clusters of the magnetic nanoparticles have been imaged. The optimization of scanning parameters that depend on the sample properties, as well as the possibility to measure the contrast arising from the single particle embedded in matrix will be discussed.
