Popis: Series of nanocrystalline Cu1-xZnxFe2O4 (x=0.2, 0.4, 0.6 and 0.8) spinel ferrites were synthesized using advanced sol-gel technique. The XRD measurements confirm the formation of cubic spinel structure in single phase for the entire sample. The average particle sizes of 14-18 nm with lattice parameter ranges from 8.38A to 8.52A were estimated. Cation distribution over the two sites of nanocrystalline Cu1-xZnxFe2O4 series, estimated from X-ray diffraction measurements is reported. The lattice parameter ‘a’ is found to be increased with increase in Zn concentration, which is attributed to the larger ionic radius of Zn compared to that of Cu.
