Abstract

We studied an evolution of local structure and medium-range ordering in relaxor ferroelectric Pb(Zn 1/3Nb 2/3)O 3 (PZN) from 550 to 15 K using neutron pair distribution function analysis. We show that the local structure of PZN is distorted at all temperatures studied. With decreasing temperature, a medium-range ordering of local polarizations develops with no global rhombohedral phase transition below T M. Instead, the crystal structure can be described as a mixture of polar nanoregions in a disordered lattice, similar to the case of Pb(Mg 1/3Nb 2/3)O 3. © 2006 American Institute of Physics.
