Thermopolarization currents in dielectrics
Kholkin A. L., Trepakov V. A., Smolenskii G. A.
Pyroelectric currents have been observed in a temperature gradient in crystals of lead magnoniobate, PBMg1/3Nb2/303, which have a center of inversion. These pyroelectric currents are accompanied by the onset of a dielectric polarization (this is a thermopolarization effect). The thermopolarization coefficient Bn has been evaluated.
