Description
0.29Pb(In1/2Nb1/2)O3-0.45Pb(Mg1/3Nb2/3)O3-0.26PbTiO3 single crystals have been studied using triple-axis based elastic and inelastic neutron scattering. Elastic diffuse scattering reveals the presence of polar nano-regions (PNR's) in this system, which emerge at the Burns temperature (TB ∼630 K) and then grow continuously in population and correlation size down to 100 K. At 300 K, characteristic “butterfly” and ellipsoid shaped diffuse scattering patterns are observed in the HK0 scattering...[Show more]
