| Abstract |
Dielectric and conductive frequency spectra in 0.01 Hz-13 MHz range have been measured for the composite consisting of PZT inclusions dispersed in LiCIO_{4}-doped polyerhylene oxide(Li_PEO) matrix with various volume fractions. The dielectric and conductive spectra of the composites revealed the relaxations related with electrode polarization and interfacial polarization. The observed spectra were reproduced using the empirical dielectric function and we could obtain various parameters related to the above two kinds of polarizations and dicussed about the parameters. |
