Synthesis and Magnetic Properties of Mn-Doped and SnO2 Nanoparticles

This paper reports the synthesis of Sn 1− x Mn x O 2 (for x =0, 0.01, 0.05 and 0.10) nanoparticles using the co-precipitation method. X-ray diffraction (XRD) results show that all samples are single phase with tetragonal crystalline structure. Rietveld refinements from XRD patterns show that the sam...

Description
Summary:This paper reports the synthesis of Sn 1− x Mn x O 2 (for x =0, 0.01, 0.05 and 0.10) nanoparticles using the co-precipitation method. X-ray diffraction (XRD) results show that all samples are single phase with tetragonal crystalline structure. Rietveld refinements from XRD patterns show that the samples present particle average sizes of 4–30 nm confirmed by scanning electron microscopy. Magnetization results for SnO 2 nanoparticles at 5% and 10% of Mn synthesized at 800 °C exhibit a ferromagnetic behavior at room temperature and an increasing of the magnetization for increasing doping concentration. On the other hand, samples synthesized at 300 °C are paramagnetic.
