Ушаков, Анатолий Васильевич. Plasma-chemical synthesis of Fe3O4 nanoparticles for doping of high-temperature superconductors [Текст] / Анатолий Васильевич Ушаков, Игорь Васильевич Карпов, Анатолий Александрович Лепешев // Journal of Superconductivity and Novel Magnetism. — 2017. — Т. 30 (№ 2). — С. 311-316Аннотация:
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.
