Neutron measurements of the low energy phonons in relaxor ferroelectric (1-x) Pb(Zn 1/3 Nb 2/3 )O 3 -xPbTiO 3 (x = 0-15%) show lattice dynamic connecting to diffuse scattering. In (200) zone, where there is no observable diffuse scattering, the effect of the diffuse on phonons is expected to be mini...

In (200) zone, where there is no observable diffuse scattering, the effect of the diffuse on phonons is expected to be minimal. A comparison of the scattering in this zone to that in (110), where significant diffuse is present, reveals strong coupling of the diffuse component to the acoustic mode.
