    Abstract: In this study, cobalt and copper ferrite compounds were prepared by co-precipitation method, the
nanocompound (Co<sub>x</sub>Cu<sub>1&#150;x</sub>Fe<sub>2</sub>O<sub>4</sub>) was then prepared by mixing cobalt ferrite and copper ferrite with different 
ratios of cobalt. The structural, morphological and magnetic properties of the resulted nanoparticles were
studied. The XRD measurements showed dominant and high peaks located at 35.54&deg; and 35.31&deg; belong to the
(311) CoFe<sub>2</sub>O<sub>4</sub> and (211) CuFe<sub>2</sub>O<sub>4</sub> planes, respectively at the same time, a decrease in grain size was observed 
with an increase in the ratio of copper ferrite as well as a decrease in the expansion of the magnetic hysteresis
ring by increasing copper ratio.
