Frequently Asked Questions (1)
Q1. What contributions have the authors mentioned in the paper "Magnetic nanoparticles for power absorption: optimizing size, shape and magnetic properties" ?

The authors present a study on the magnetic properties of naked and silica-coated Fe3O4 nanoparticles with sizes between 5 and 110 nm. The results show a strong dependence of the SPA with the particle size, with a maximum around 30 nm, as expected for a Néel relaxation mechanism in single-domain particles.
