| dc.description.abstract | The synthesis, characterization and dielectric properties of Praseodymium substituted calcium manganese oxides [PrxCa2-xMnO4] compounds were investigated. The dielectric properties of these compounds were studied in the frequency range from 20 Hz to 1 MHz between 10 K and 300 K.
The low temperature dielectric properties were studied for the x = 0 ~ 0.5 compounds. Dielectric permittivity, dissipation factor, activation energy with thermally activated process, modulus spectra, and Cole-Cole plot have been investigated. The ε'(T) curves of samples show that the value of real dielectric permittivity has apparent high value (ε' ~ 104) near 270 K for x = 0.2, 0.3, 0.4, 0.5. The tanδ(T) curves of these compounds exhibit dielectric relaxation at low temperature. The highest values in M”-T relation are found to increase with increasing with increasing x for the PrxCa2-xMnO4 system. The peak temperatures of tanδ shift from low to high temperatures as the test frequency increases in all samples. In these samples we also observed Jonscher power law behavior. | en |
