Abstract
This paper presents recent results on magnetic interactions in CoPt:C nanoc rystalline films and Co:C magnetic nanodot arrays. The local magnetic prope rties were studied by magnetic force microscopy. We discuss the limit of th e using DeltaM 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 coupli ng between the dots. (C) 2001 Acta Materialia Inc. Published by Elsevier Sc ience Ltd. All rights reserved.
