Description
A study of magnetic properties of bulk and fine powders of (Zn,Cu,Cd)0.5Ni0.5Fe2O4 oxides by Mossbauer spectroscopy and magnetization measurements is presented. The evolution of grain sizes derived from X-ray diffraction (XRD) is also presented. The Mossbauer spectra for fine powders show a combination of ferrimagnetic and paramagnetic behavior. The magnetic transition temperature, TC decreases with reduced grain size for the Cd-based oxide. An anomalous increase in TC is observed for the Zn-based oxide. The increased coercivity with milling is associated with reduced grain size and increased grain boundaries
