Opis:: UHV deposited magnetic Co/Cu multilayers were investigated by means of scanning tunneling microscopy (STM) and atomic force microscopy (AFM). Surface of the sample i.e. upper covering layer in "plane" configuration and individual sublayers in "cross-section" configuration were investigated. A possibility of structure characterization of metallic multilayers by STM and AFM in the cross-section configuration is demonstrated.

Opis:: We report on imaging of isolated, few nanometers in size, magnetic dots (Co, Ni) by the use of a scanning tunneling microscope equipped with a ferromagnetic Co tip in the presence of external magnetic field. The dependence of apparent height of dots as a function of magnetic field takes a hysteresis-like shape. We discuss possible mechanisms of the scanning tunneling microscope tip interactions with dots.

Opis:: Novel nanometer scale structures have been produced by thermal heating or laser irradiation on the surface of single- and multi-layers of C$\text{}_{60}$ and C$\text{}_{84}$ on Si. These structures were examined by combined measurements of scanning tunneling spectroscopy and high resolution electron energy loss spectroscopy. The results show specific chemical reactions of substrate with carbon clusters having single- and double-bonded network. Covalent bonds are formed in some of these chemical reactions.

Opis:: Co, Fe and Ni clusters of nanometer size, deposited on silicon and graphite (highly oriented pyrolytic graphite), were observed by a scanning tunneling microscope. Deposition as well as the scanning tunneling microscope measurements were carried out in an ultrahigh vacuum system at room temperature. Detailed analysis of Co cluster height was done with the scanning tunneling microscope equipped with a ferromagnetic tip in the magnetic field up to 70 Oe. It is found that bigger clusters (few nanometers in height) exhibit a dependence of their apparent height on applied magnetic field. We propose that such behaviour originates from the ferromagnetic ordering of cluster and associate this effect to spin polarized tunneling.
