Sn1-xFexO2 nanoparticles (x = 0, 0.05, 0.10 and 0.15) were synthesized by co-precipitation. X-ray diffraction and electron diffraction images showed that only rutile type phase was present in the samples. Electron microscopy was used as a tool for revealing morphology, distribution size and structure characteristics of the nanoparticles; while Energy Dispersive X-Ray Spectroscopy analysis confirmed the selected stoichiometry. Fe-57 and Sn-119 Mossbauer spectroscopy at Room Temperature showed a lattice disorder induced by the incorporation of Fe ions in the structure. No magnetic hyperfine ordering was detected for Fe-57 probes and the asymmetry in their quadrupolar splittings is explained as a texture effect at the nanoparticles shells. Quadrupolar splitting at Sn-119 probe reached a maximum for x = 0.1, being this fact attributable to a highest distorted environment. Magnetic hysteresis loops were measured at different temperatures showing, for Fe doped samples, a combination of paramagnetism and weak ferromagnetism. (C) 2016 Elsevier B.V. All rights reserved.
