Abstract

This paper presents recent results on magnetic interactions in CoPt:C nanocrystalline films and Co:C magnetic nanodot arrays. The local magnetic properties were studied by magnetic force microscopy. We discuss the limit of the using ΔM for characterization of magnetic interactions in these CoPt:C nanocrystalline films. The magnetic force microscopy images of patterned Co:C nanodot arrays show the presence of "macro"-domains (domains formed by several separate dots). This behavior is attributed to the exchange coupling between the dots.
