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 ...
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 ...
