Polaronic transport in NaNbO
Measurements of the temperature dependence of the dc conductivity and the Seebeck coefficient were performed for polycrystalline samples of stoichiometric sodium niobate. The measurements were made in the temperature range ...
Electrical properties of Na[0.98]Li[0.02]NbO under axial pressure in phase transition region
The measurements of electric properties of Na[0.98]Li[0.02]NbO ceramics for stress-free or samples under stress have been carried out. It was found that incorporation of Li-cations (2% mol) in antiferroelectric NaNbO ...
Dielectric properties of Li[0.003]Na[0.997]NbO ceramics
Temperature, frequency and time dependencies of dielectric permittivity and pyroelectric current of Li[0.003]Na[0.997]NbO ceramics have been presented. Investigation of the pyroeffect reveals the existence of the local ...
Investigation of dielectric properties of Li[x]Na[1−x]NbO ceramics for x = 1 and x = 4
The a.c. electrical response of Li[x]Na[1−x]NbO (LNN) solid solution in low frequency range (100 Hz–20 kHz) has been analysed as a function of temperature (300 K–750 K). A complex picture of the dependence of the ...
Temperature and time changes electric permittivity in sodium niobate
Temperature and time dependencies of electric permittivity of sodium niobate have been measured. The dispersion and time changes of electric permittivity for NaNbO ceramic has been observed. Results of this investigations ...
