MAGNETIC-PROPERTIES OF ZINC DOPED FERRITES

A series of samples of the system Co1-xZnxFe2O4 (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 Co2+ by Zn2+ furnish new significant fact concerning the magnetic behaviour of ferrites. The magnetic strength of the magnetic ions on the B and A-sites A-sites can be varried relative to each otherby the substitution of Zn2+. The increase of density of the composition increases the magnetic interaction of the dipole moment at the B-sites.
