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 ...
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 ...
