Abstract

Magnetic force microscopy (MFM) measurements were performed on monodispersed single-domain nickel nanospheres fabricated by the microwave-assisted (MW) polyol method. As found by MFM, a relevant characteristic of these spheres with a size distribution in the 100-180 nm range is the magnetic stripe domain structure. The obtained highly globular nanostructures of Ni_coreNiO_shell were measured by XRD, TEM, XPS, and EDAX. The ferromagnet/antiferromagnet interface coupling is discussed with the results of VSM and SQUID. The relation of the exchange-coupling field with particles sizes is evaluated.
