SOFT-MODE SPECTRA AND PHASE TRANSITION IN KDP CRYSTAL WITH ADP IMPURITIES
1981
Le Journal de Physique Colloques
Preserved Fulltext
On the basis of the q-dependent coupling interactions between the proton pseudo-spin mode and the lattice phonon mode we could explain qualitatively the observation that the ferroelectric transition temperature of the KDP crystal was lowered as the ADP impurity concentration in the crystal was increased.
