摘要：

We report Mossbauer spectroscopy and magnetization studies of MgxCa1-xFe2O4 (0 <= x <= 1.0) nanoferrites. The crystallite size varies between 9 am and 15 nm. The properties were investigated by X-ray diffraction (XRD), Fe-57 Mossbauer spectroscopy and magnetometry. The XRD results indicate pure cubic spinet 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 Mg2+ ion concentration. (C) 2014 Elsevier B.V. All rights reserved.
