Abstract:

CuFe2O4 nanoparticles and (CuFe2O4)(0.95)(SnO2)(0.05) nanocomposites were studied by XRD, Mossbauer spectroscopy and SQUID magnetometer. The XRD pattern shows the well-defined sharp peaks characterized tetragonal structure of CuFe2O4. The Mossbauer 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.{''}.
