Electric field induced monoclinic phase stability in Ca doped Na0.5Bi0.5TiO3: Case of 0.93Na0.5Bi0.5 TiO3 – 0.07CaTiO3 ferroelectric ceramics
The ferroelectric perovskite complex 0.93Na0.5Bi0.5TiO3 – 0.07CaTiO3 (NBT –0.07CT) ceramics were studied by a simple X-ray diffraction upon application of an increasing electric field. It is shown that the field induced rhombohedral (R3c) to monoclinic (Cc) phase transition at room temperature. This...
