Abstract
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.
