J. Bornarel et R. Cach, PHASE COEXISTENCE IN DKDP WITH A THERMAL-GRADIENT PARALLEL TO THE FERROELECTRIC AXIS, Journal of physics. Condensed matter, 6(9), 1994, pp. 1663-1676
The coexistence of the paraelectric and ferroelectric phases is repone
d for thermally gradiented samples of DKDP; the shape of the phase fro
nt, the relevant domain textures and the dielectric properties are des
cribed. A phenomenological model allows us to evaluate the contributio
n of the domains to the dielectric constant.
