Investigation of ferroelectric order-disorder type compounds with asymmetric double-well potential
R. R. Levitskii, T. M. Verkholyak, I. V. Kutny +1
The Mitsui model for the order-disorder type ferroelectrics is studied within the mean field approximation. The phase diagram of the model is obtained, its dependence on the transv…

Hydrostatic pressure influence on dielectric permittivity of KH2PO4 and KD2PO4 in the piezoelectric resonance region
R. R. Levitskii, A. G. Slivka, A. P. Moina +2
We measured transverse and longitudinal dielectric permittivities of KDP and DKDP in the piezoelectric resonance frequency region under the hydrostatic pressure. The transverse per…
