Abstract | ||||
Bulk materials of Mn doped Pb(Zr0.53Ti0.47)O3 of composition close to the morphotropic phase boundary have been prepared by solid state route. The influence of various Mn contents, 0.004 , 0.008 and 0.016, on the perovskite type structure of the materials are examined using XRD technique. The types of Mn-ions substitution in the original structure are considered with respect to deviation from the ideal tolerance value (t = 1). The results confirmed the presence of two coexisting perovskite unit cells, tetragonal and rhombohedral, throughout the various compositions used and the rhombohedral phase becomes dominant at higher Mn contents. An attempt is also made using Rietveld to establish the exact location of the various ions displacements in the tetragonal unit cells. | ||||
