摘要：
Magnetic force microscopy (MFM) analyses were done to investigate the magnetization reversal behaviour of a perpendicular patterned CoCrPt medium. The medium was observed by using in-situ (in the presence of perpendicular field up to 5.5 kOe) and ex-situ (in the absence of external field) MFM techniques. Magnetization state, coercivity and magnetostatic energy of the individual magnetic dots were studied in a given microscopic area. Taking account of the magnetostatic energy for the respective nanomagnets, the maps of the experimental and intrinsic coercivities for this region were obtained. (C) 2004 WILEY-VCH Verlag GmbH & Co.
