Аннотация: Sn–O nanoparticles were prepared by levitation-jet aerosol synthesis and found to exhibit ferromagnetic behavior. X-ray powder diffraction analysis and ¹¹⁹Sn Mössbauer spectroscopy confirmed these nanoparticles consist of β-Sn, SnO and SnO₂ phases. The maximum specific magnetization was observed for nanoparticles containing the SnO/SnO₂ interface.

Ключевые слова: levitation-jet generator, nanoparticles, tin monoxide, tin dioxide, Mössbauer spectra, room-temperature ferromagnetism, X-ray diffraction.
