Abstract

High-energy resolution neutron spin-echo spectroscopy has been used to measure the intrinsic width of diffuse scattering discovered earlier in relaxor ferroelectric crystals. The anisotropic and transverse components of the scattering have been observed in different Brillouin zones. Both components are found to be elastic and have been measured within an experimental accuracy of 1 μeV. The possible physical origin of the static-like behavior is discussed for each diffuse scattering contribution.
