    Direct observation of nano-polar-domain phase transition in PLZT ceramics by SANS
    (The Bragg Institute, Australian Nuclear Science and Technology Organisation, 2005-11-27) Fei, Y; Piltz, RO; Choy, CL; Lou, HS; Xi, TG; Strunz, P
    Small Angle Neutron Scattering (SANS) measurements on Pb(0.92) La(0.08) Zr(0.60) Ti(0.40) O3 (PLZT) ceramics reveals that the ferroelectric phase experiences the evolution into nano-polar-domain (NPD) around the ferroelectric phase transition temperature Tc. This NPD gradually diminished as the temperature increased above the Tc. This director observation gives a strong support on the theory of nanometer-sized polar regions responsible for the extra larger ferroelectric and dielectric constant in this system. © The Authors
