dc.description.abstractWe present a Study on the magnetic properties of naked and silica-coated Fe₃O₄nanoparticles with sizes between 5 and 110 nm. Their efficiency as heating agents was assessed through specific power absorption (SPA) measurements as a function of particle size and shape. The results show a strong dependence of the SPA with the particle size, with a maximum around 30 nm, as expected for a Neel relaxation mechanism in single-domain particles. The SiO₂shell thickness was found to play an important role in the SPA mechanism by hindering the heat Outflow, thus decreasing the heating efficiency. It is concluded that a compromise between good heating efficiency and surface functionality for biomedical purposes can be attained by making the SiO₂functional coating as thin as possible.
