摘要：

In the probably first successful photon correlation spectroscopy experiment on a crystalline solid, inelastic light scattering of vibrating random-field-pinned domain walls has been observed at subkilohertz frequencies in the uniaxial relaxer ferroelectric Sro(0.61-x)Ce(x)Ba(0.39)Nb(2)O(6). In the paraelectric relaxer phase the response of polar nanoclusters becomes overdamped and Rayleigh-like.
