Co-precipitation technique is used for preparing the composites of CoFe 2 O 4 /VZnO. The effect on the variation on the size of the crystals of CoFe 2 O 4 is studied by varying the annealing temperature over the range from 500°C to 900°C. The structure of composite powder obtained after annealing was studied by Rietveld refinement and XRD. The estimation of the crystalline phases of the sample is done by XRD though Rietveld refinement. The space group and structure of zinc oxide was observed as P63mc(186) and hexagonal while that for the cobalt ferrite was Fd3m(227) and cubic. The values of all R factors was calculated and the effect of annealing temperature on the size of the crystal was discussed.
