研究了Pb（Mg 1/3 Nb 2/3）O 3单晶在297 K下的低频光散射谱。一个准弹性散射被发现，其线形被确定为“幂律”型，而不是一个单一的洛伦兹曲线或两个洛伦兹曲线的叠加。幂律谱意味着弛豫子中弛豫时间的广泛分布。
The low-frequency light-scattering spectrum in Pb(Mg1/3Nb2/3)O-3 single crystal is investigated at 297 K. A quasielastic scattering is found, and its line shape is identified as a "power-law" type, instead of a single Lorentzian or superposition of two Lorentzian curves. The power-law spectrum implies the existence of a wide distribution of relaxation times in relaxors.
