Abstract Ferrite nanoparticles (Fe3O4) have been produced
by the direct low-pressure plasma-chemical synthesis.
X-ray diffraction (XRD), high-resolution transmission
electron microscopy (HRTEM), vibration magnetometry
(VSM), and Mössbauer spectroscopy (NGR) were used
for measurements, showing that the produced nanoparticles
have an average size of 9.4 nm, a crystalline phase of magnetite,
possess a property of superparamagnetism at room
temperature, and have a blocking temperature of 89 K. The
peculiarities of nanoparticle behavior in the magnetic field,
related to a large specific surface area, are discussed.
