Theory of the transition in kh2po4
WebbDynamical aspects of the ferroelectric phase transition in KH 2 PO 4 -type crystals are elucidated on the basis of the coupling between the proton tunneling mode and the … Webb1 nov. 1999 · A ferroelectric KH2PO4 crystal is implemented in a simple series connection of an RLC circuit and the transition to chaos near the phase-transition temperature is investigated. The torus-doubling scenario to chaos, the theory of which was expounded by Kaneko for high-dimensional dynamical systems, has been found in the crystal.

WebbWe propose a new model for the ferroelectric phase transition of KH2Ø4-type crystals. The proton tunneling mode is found to be strongly coupled with the optical mode of the [K-P041 lattice vibrations along the c -axis via electrostatic Coulomb interaction.

WebbOur measurements indicate a sharp phase transition preceding the increase in the vapour pressure of water. We carefully checked the loss of weight of KH2PO4 and KD2PO4 crys- tals that had just crossed the transition point and found it to be less than 0. 15 per cent, indicating almost no escaping of water outside of the crystal.
