Thermopolarization effect in an incommensurate phase of a crystal
Kallaev S. N., Abdullaev A. A., Gladkii V. V.
An anomalous thermopolarization effect has been observed in the incommensurate phase of the ferroelectric Rb2ZnCl4. Specifically, the dielectric polarization induced by a temperature gradient has a nontrivial temperature dependence and does not vanish when the gradient is reduced to zero. The relationship between the anomalies in this effect and features of other physical properties of incommensurate phases is discussed.
