The Fe3+ ions in BaFe12O19, were partially substituted by Zn2+ and Ti4+ ions. This paper reports the study of the dielectric properties of the compounds BaFe12-2xZnxTixO19 (x = 1, 1.5, 2) synthesized using the solid state diffusion method. The plots of variation between real (Z') and imaginary (Z'') parts of impedance show the decrease of grain resistance with increase in temperature as well as concentration of substitution (x). In these plots the shift in the peak positions of the semi-circles with the change in temperature suggests the variation of relaxation time which indicates thermally activated conduction mechanism. The variation of M' and M'' (real and imaginary parts of dielectric modulus respectively) with frequency has also been carried out in the present study. The value of M' increases with increase in frequency at various temperatures.
