Abstract
Abstract The present study reports the structural and morphological investigation of La 3+ doped BaTiO 3 nanoceramics prepared by combustion synthesis. The effect of La 3+ doping on the structural and morphological properties was examined by the X-Ray diffraction (XRD), transmission electron microscopy (TEM) and selected area electron diffraction (SAED) technique. Room temperature XRD analysis shows that prepared samples are in a single phase with the tetragonal structure. Structural parameters like average crystallite size ( D ) and lattice constant ( a and c ) were calculated from the XRD data. The surface morphology of the samples was studied by transmission electron microscopy (TEM) technique. It was found that the nanoparticles are in tetragonal shape with agglomeration to the some extent. All the outcomes show that La doped BaTiO 3 nanoceramics are promising candidates for spintronic applications.
