- 論文の詳細を見る
The dielectric dispersion associated with the ferroelectric phase transition inLi.Ge.O.. has been measured in the frequency range from 21 MHz to 7 GHz aroundthe Curie point, T.= l0.4'C. The Debye type dispersion which showed a critical slow-ing-down of dielectric response was observed, its relaxation frequency being about lGHz at T.. The relation between the observed critical slowing-down and the softeningof the optical phonon reported previously is discussed.[dielectric dispersion, dielectric relaxation, complex dielectric constant, dielectric lf critical slowing-down, ferroelectric Li.Ge,O., experimentl
