Resumo
Ferrite Fe3O4 nanoparticles have been formed in low-pressure arc discharge plasma. It has been shown that the obtained nanoparticles have an average size of 9.4 nm and a blocking temperature of 89 K, crystallize in the magnetite phase, and are superparamagnetic at room temperature. The features in the behavior of nanoparticles in a magnetic field related to their large specific surface are discussed.
