Investigation of structural, optical and magnetic properties in PbTi1−xFexO3 ceramics

We have been successful in preparation of PbTiO3 by partly substituting Ti site by Fe ions using solid state reaction method. PbTi1−xFexO3 perovskite has been studied as a function of Fe concentration using X-ray diffraction, absorption, Raman scattering and magnetization measurements. PbTi1−xFexO3 system exhibits ferromagnetic ordering at room temperature. There appears an anomalous change in the lattice constants, optical band gap, Raman spectroscopy as well as magnetization of sample with x = 0.30. The result also suggests the limit of dissolubility of Fe ions doped in PbTiO3.
