A series of samples of the system Co_{1-x}Zn_{x}Fe_{2}O_{4} (x = 0.0, 0.3, 0.4, 0.5 and 0.8) have been prepared by the usual ceramic technique. X-ray analysis shows that they are cubic spinel (single phase). The lattice parameter a and the bulk density D are measured for the samples. The substitution experiments replacing Co^{2+} by Zn^{2+} furnish new significant fact concerning the magnetic behaviour of ferrites. The magnetic strength of the magnetic ions on the Band A-sites can be varried relative to each other by the substitution of Zn^{2+}. The increase of density of the composition increases the magnetic interaction of the dipole moment at the B-sites.
