Mossbauer Spectroscopic Investigations of Fe Doped SnO2 powders
EMSL Project ID
8994
Abstract
Recently we have successfully developed Fe doped SnO2 which are ferromagnetic and semiconducting at room temperature. Our detailed structural and morphological studies using x-ray diffraction and transmission electron microscopy showed the formation high purity single phase samples of nanoscale dimensions. Magnetic measurements showed strong ferromagnetic which are very different from metallic iron or their known oxides. We are now employing Mossbauer Spectroscopy to investigate the oxidation state and interactions of the inclorporated Fe ions.
