Degenerate rhombohedral and orthorhombic states in Ca-substituted Na0.5Bi0.5TiO3 (2009)
Ranjan, Rajeev, Kothai, V, Garg, Rohini, Agrawal, Anupriya, Senyshyn, Anatoliy, Boysen, Hans
Neutron powder diffraction and temperature dependent dielectric studies were carried out on Ca-substituted Na0.5Bi0.5TiO3, i.e., (Na0.5Bi0.5)(1-x)CaxTiO3. Stabilization of an orthorhombic phase even...
Kalyani, Ajay Kumar, Garg, Rohini, Ranjan, Rajeev
The system (1-x)PbTiO3-(x)BiAlO3 has been investigated with regard to its solid solubility, crystal structure, microstructure, and ferroelectric transition. The unit cell volume and the tetragonality...
Structure and phase transition of Na0.5La0.5TiO3 (2008)
Garg, Rohini, Senyshyn, Anatoliy, Boysen, Hans, Ranjan, Rajeev
A temperature dependent neutron powder diffraction study was carried out on Na0.5La0.5TiO3 (NLT) from 298 K up to 1373 K. Rietveld analysis using high resolution x-ray and neutron powder diffraction...
