Abstract

Anomalous behaviour of ε and tan δ in the paraelectric phase was found for PbZr0.992Ti0.008O₃ single crystal. In the vicinity of temperatures 280–290°C (T _c = 236°C) the pyroelectric effect was also observed. Using the data obtained, the existence of an additional polarization (polar regions oriented in an external electric field) in the paraelectric phase is discussed.
