Title

Dynamics of nanoscale polar fluctuations in PMN

Abstract

We intend to do continuing study of a Vogel-Fulcher relaxation in the relaxor ferroelectric Pb(Mg1/3Nb2/3)O3 single crystal via investigation of its diffuse scattering. This study will give valuable information about time-space correlation lengths of polar fluctuations associated with exceptional dielectric properties of multiaxial relaxor perovskites. In this challenging study, we would like to take advantage of fixed window measurements on the new high-flux IN16B backscattering spectrometer and our experience with this type of experiment.
