Abstract
Dense monolayer assemblies of iron oxide nanoparticles have been obtained on large areas using the Langmuir-Blodgett technique. The density and ordering of the film were found to depend on the quality of the nanoparticle suspensions, which should display monodisperse nanoparticles and no free molecules. A modification of nanocrystals magnetic properties was noticed between the random configuration (powder sample) and the assembly in monolayer (Langmuir-Blodgett). The organisation in film is suggested to induce an enhancement of magnetic interactions.
