Abstract

The magnetic remanent states and chemical compositions of chains of crystalline Fe xNi 1-x nanoparticles, which have an average size of 50 nm, have been characterised using off-axis electron holography and image spectroscopy. The critical sizes at which the particles can support magnetic vortices are correlated with their compositions. A significant increase in magnetic vortex core diameter is observed when vortices in the nanoparticles are aligned parallel to the chain axes.
