Magnetic structural properties of maghemite nanoparticles obtained with the use of different stabilizers

Resumo

By co-deposition maghemite particles doped with Sm³⁺ are obtained with the average particle size within 9.9-10.9 nm. Samarium is shown to be present mainly in the near-surface layer of nanoparticles. It is found that the functionalization of the maghemite nanoparticle surface by organic molecules does not deteriorate their magnetic properties.
