XRD, Mossbauer and magnetic properties of Mg sub(x)Co sub(1-x)Fe sub(2)O sub(4) nanoferrites

We report Mossbauer spectroscopy and magnetization studies of Mg sub(x)CO sub(1-x)Fe sub(2)O sub(4) (0 [< or =] x [< or =] 1.0) nanoferrites. The crystallite size varies between 9 nm and 15 nm. The properties were investigated by X-ray diffraction (XRD), super(57)Fe Mossbauer spectroscopy and...

Description
Summary:We report Mossbauer spectroscopy and magnetization studies of Mg sub(x)CO sub(1-x)Fe sub(2)O sub(4) (0 [< or =] x [< or =] 1.0) nanoferrites. The crystallite size varies between 9 nm and 15 nm. The properties were investigated by X-ray diffraction (XRD), super(57)Fe Mossbauer spectroscopy and magnetometry. The XRD results indicate pure cubic spinel structure for all the compounds. The evolution of the properties has been explained on the basis of Mg content and crystallite sizes. The Mossbauer and magnetization results show strong dependence of the properties on crystallite size and non-magnetic Mg super(2+) ion concentration.
