Abstract

A study was performed on colloidal iron nanoparticles with a core size of 10.6 nm using magnetic force microscopy. It was found that single nanoparticles were more prominently visible in magnetic force gradient images than clusters. The local field produced by a cluster of particles was sufficient to align their moments in the plane of the cluster. An alternative possibility of spin glass formation within clusters was also considered.
