Title: K<sub>0.9982</sub>Li<sub>0.0018</sub>TaO<sub>3</sub>Crystal Under External DC Electric Field
Abstract: The influence of external dc electric field on dielectric properties of K1-xLixTaO3 x = 0.18% (henceforth KLT-x%) is presented. Electric permittivity dependence on dc electric field confirms the existence of short-range electric order. According to the suggestion made by us [1 Kaszyńska, K., Trybuła, Z., Glinchuk, M. D., Bykov, I. P. and Laguta, V. V. 2005. The local order in KTaO3 admixtured by the ions of Li+. A. Phys. Pol. A, 108: 379–383. [Crossref] , [Google Scholar]] the substitution of K+ ions by off-center Li+ in KTaO3 is considered as the source of induced polar clusters of short range order at low temperatures for this crystal. The low-temperature state of KLT-0.18 may be considered as a quantum superparaelectric one that may be toggled into an improper ferroelectric while applying an electric field [2 Dec, J., Miga, S., Kleemann, W., Trybuła, Z. and Kaszyńska, K. 2010. Does highly dilute KTaO3: Li undergo collective glassy freezing?. Ferroelectrics., 399: 118–122. [Taylor & Francis Online], [Web of Science ®] , [Google Scholar]] or a chiral glass state [3 Dec, J., Miga, S., Trybuła, Z., Kaszyńska, K. and Kleemann, W. 2010. Dynamics of Li+ dipoles at very low concentration in quantum paraelectric potassium tantalate. J. Appl. Phys., 107: 094102[Crossref], [Web of Science ®] , [Google Scholar]].
