Abstract:

The preparation of ordered two-dimensional 2-D magnetic nanoparticles using a magnetophoretic technique is reported. The quality of the ordering can be readily observed by electron microscope and the lattice constants determined by electron difficaction. Using image processing, it can be shown that the cobalt particles condense into hexagonal close packing and also that the crystallographic axes of the individual cobalt particles are randomly oriented. The equilibrium distance between the particles corresponds approximately to the size of the absorbed stabilisers and the strength of the magnetic field. The method is of general interest as a means of preparing monolayer film of nanosized magnetic particles such as cobalt or iron oxide.
