Abstract
The influence of Samarium substitution on the dielectric properties of modified PZT composition with representative formula [Pb1âxSmxZr0.588Ti0.392Fe0.01Nb0.01O3] system is reported. Samarium (Sm) was varied from 0 to 0.01/FU in the present system in a step of 0.0025. The samples were prepared by the traditional solid state reaction process. XRD analysis showed all the samples to be single phase with tetragonal structure. Dielectric properties were studied in detail as a function of frequency and temperature (from room temperature (RT) 30 to 400 °C). All compositions show phase transition and the transition temperature (TC) is found to decrease with increase in Sm substitution. Room temperature dielectric constant shows an increasing trend while loss improves with Sm doping.
