Abstract

In the present paper, effect of cobalt (Co) substitution on dielectric behavior of Ba(Ti0.85 Sn0.15)O3 , which exhibits a broad maxima near room temperature in its ε' vs. T plots has been studied. Compositions with x = 0.01 and 0.03 in the system Ba(Ti0.85-x Cox Sn0.15)O3 were prepared by solid state ceramic method. Dielectric properties of the compositions were studied using Novocontrol α-S High Resolution dielectric analyzer as a function of temperature in the frequency range 1 Hz-1 MHz. Both the compositions (x = 0.01 and 0.03) exhibited a diffuse phase transition behavior similar to x = 0.00. Diffuseness of phase transition was determined by full width at half maxima (FWHM) in ε' vs. T plots. FWHM increases with increasing cobalt substitution. In hysteresis loop measurement, a decrease in coercivity and remanent polarization has been found with increasing Co concentration.
