Abstract:

CuFe2O4 nanoparticles and (CuFe2O4)0.95(SnO2)0.05 nanocomposites were studied by XRD, Mössbauer spectroscopy and SQUID magnetometer. The XRD pattern shows the well-defined sharp peaks characterized tetragonal structure of CuFe2O4. The Mössbauer spectrum of CuFe2O4 showed ferrimagnetic structure while spectrum of (CuFe2O4)0.95(SnO2)0.05 composite demonstrated a mixture of ferrimagnetic and paramagnetic components. The D.C. magnetization revealed that SnO2 addition leads to overcoming the "superparamagnetic limit.". © Springer Science + Business Media B.V. 2006.
