Thermally Induced Solid-State Route toward Magnetite Nanoparticles with Controlled Stoichiometry
Original language description
Nonstoichiometric magnetites can potentially play significant role in many physical, chemical, and biomedical applications due to their variable and controllable magnetic properties. We carried out thermally induced solid-state preparation of nonstoichiometric magnetites with various degree of stoichiometry using high-temperature reaction chamber of an X-ray powder diffractometer by maghemite reduction by hydrogen gas in the temperature range between 145 and 200 degrees C. Subsequently, the prepared samples were characterized in details by Fe-57 Mossbauer spectroscopy, X-ray powder diffraction, and magnetization measurements. Fe-57 Mossbauer spectroscopy served as a tool for the stoichiometry quantification of the prepared samples comparing the relative areas of subspectra components. Stoichiometry of the prepared magnetite samples varied between 0.31 and 0.45. Cubic (53 wt.%) and tetragonal (47 wt.%) maghemite substructures were identified in X-ray powder diffraction patterns of the p
