Scanning tunneling microscopy/spectroscopy as well as atomic force microscopy were applied to study the non-structural and nanoelectronic properties of periodic nickel nanoparticles deposited on n-silicon substrates. Periodic nickel (Ni) nanoparticles were prepared by using nanosphere lithography and analyzed by scanning tunneling microscopy/spectroscopy and atomic force microscopy. By the evaporation of Ni perfectly ordered nanoparticles were produced and very good correlation between latex mask was observed. Finally, tunneling spectroscopy performed with non-magnetic tip yield information about local electronic properties of nanoscale structures at surface.

The ferrite magnetic nanoparticles with core-shell structures were obtained in two step preparation process. The Mössbauer spectra obtained for particles of pure maghemite or magnetite and two layered core-shell one the magnetite on maghemite and maghemite on magnetite are very different from each other. The presented results show that interparticle and intraparticle interaction plays important role in overall magnetic properties as well.

A systematic study of the magnetic properties of submicron equilateral Ni triangles is reported. The triangular shape is a result of the particular preparation method used, which is based on a new kind of nanosphere lithography technique. In this case, the magnetic material is deposited through a latex sphere mask, yielding a periodic hexagonal array of in-plane magnetised triangular shaped elements. The magnetic properties were investigated as a function of thickness by magnetic force microscopy, superconducting quantum interference device magnetometry and vibrating sample magnetometry.

A method of obtaining large-scale 2D arrays of ordered metallic nanoparticles is presented. The arrays were prepared using nanosphere lithography based on the self-assembly of latex particles on a water surface. Using 496 nm and 1040 nm diameter particles, it was possible to prepare arrays of over one cm^2, with defect-free areas of over 50μ m^2. By the evaporation of nickel or gold, periodic metallic particle arrays were produced. Modification of the particle array morphology was also shown by using double-layered masks. Computer simulated mask models were used to reveal interesting morphologies obtainable by the application of multilayered masks.
