Effect of Dilute Magnetic ions on the Optical, Dielectric and Ferroelectric properties of PZT at Morphotopic Phase Boundary

摘要

Modified-PZT ceramics with a formula Pb_(0.9)Ni_(0.1)[(Zr_(0.52)Ti_(0.48))]_(1-x)Sn_xO3 located near the morphotropic phase boundary (MPB) were prepared by conventional solid state process to investigate effects of dilute doping of Ni and Sn in different sites of PZT. The single phase structure of the series of samples has been identified by x-ray diffraction technique. The optical band gap has been obtained from the UV-Vis spectra and found to be shrinkage with doping. The detail dielectric and impedance studies are being carried out to investigate the conduction mechanism of the samples. A significant enhancement in the electric polarization is observed for the maximum Sn doping in a modified PZT.
