Temperature and time changes electric permittivity in sodium niobate
(1997)
Temperature and time dependencies of electric permittivity of sodium niobate have been measured. The dispersion and time changes of electric permittivity for $NaNbO_3$ ceramic has been observed. Results of this investigations ...
Electrical properties of $Na_{0.98}Li_{0.02}NbO_3$ under axial pressure in phase transition region
(2003)
The measurements of electric properties of $Na_{0.98}Li_{0.02}NbO_3$ ceramics for stress-free or samples under
stress have been carried out. It was found that incorporation of Li-cations (2% mol) in antiferroelectric ...
Investigation of dielectric properties of $Li_xNa_{1−x}NbO_3$ ceramics for x = 1 and x = 4
(1999)
The a.c. electrical response of $Li_xNa_{1−x}NbO_3$ (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 ...
Effect of compressive stress on dielectric and ferroelectric properties of 0.25PSN-0.75PLuN ceramics
(2003)
The PSN-PLuN solid solutions have been prepared in the whole composition range for the first time. The
dielectric, pyroelectric and hysteresis loops measurements of the 0.25PSN-0.75PLuN ceramics stress-free or under
the ...
Dielectric properties of $Li_{0.003}Na_{0.997}NbO_3$ ceramics
(1998)
Temperature, frequency and time dependencies of dielectric permittivity and pyroelectric current of $Li_{0.003}Na_{0.997}NbO_3$ ceramics have been presented. Investigation of the pyroeffect reveals the existence of the ...
