Abstract

Structures of PbHfO3 between 100 K and 500 K were analyzed by Rietveld method using synchrotron radiation. Disordered arrangement of Pb atoms in the cubic phase was found as in PbZrO3. The average of Pb shifts and the square root of lattice distortion showed the similar dependence on temperature as expected from a phenomenological theory.
