概要:

Far infrared reflection spectra of complex perovskite-type ceramics, Ba (Zn_<1/3>Ta_<2/3>) 0_3, Ba (Ni_<1/3>Ta_<2/3>) 0_3 and Ba (Mn_<1/3>Ta_<2/3>) O_3, were measured in the frequency range between 100 and 4000 ^cm<-1> at room temperature with a Fourier transform infrared spectrometer. The data were analyzed according to the Kramers-Kronig relation. The Q-values of these ceramics were discussed using the obtained dispersion … parameters, and the reason was given why the former two ceramics showed better Q-values than the latter one. A possibility that the presence of other vibration-modes affecting the dielectric constants and Q-values of the materials in the frequency range below 100cm^<-1> was discussed. 続きを見る
