Description

The construction of novel nanostructured materials attracts much attention in materials research due to possibilities for contributions in low-dimensional research and/or in potential technological applications. In this communication we present the formation of ordered arrays of γ-ferrite nanoparticles (NP) by the Langmuir-Blodgett technology (layer-by-layer deposition) and characterization of the magnetic properties by Moessbauer spectroscopy and vibrational magnetometry. The effect of a non-ideal dispersion of particle size on the phase transition from superparamagnetic to ferromagnetic state of the 2D nanoparticle system is discussed from the viewpoint of potential applications.
