J. Bornarel et al., DIELECTRIC MEASUREMENTS DURING PHASE COEXISTENCE IN DKDP CRYSTALS UNDER ROTATING THERMAL-GRADIENT, Journal of physics. Condensed matter, 8(50), 1996, pp. 11337-11350
The dielectric properties of DKDP samples under a thermal gradient G(e
) are studied versus the orientation of G(e) relative to the c ferroel
ectric axis. Simple models allow us to explain the variation of the di
electric constant in the paraelectric phase, and also demonstrate a co
ntribution due to the phase front existence for the first time.
