We calculate the spontaneous polarization as a function of temperature for a mixed crystal of Pb1-xCaxTiO3 close to the tricritical pointdx (x = 0.4). This calculation of the spontaneous polarization is performed using the effective field approximation for the dipolar (PbTiO3) and higher order ( quadrupolar and octopolar) interactions for the mixed system of Pb1-xCaxTiO3 at concentrations from x = 0 to x = 0.45.

Analysis of the dielectric constant, spontaneous polarization and the coersive field close to the phase transitions in ferroelectric K2CoCl4 Yurtseven, Hasan Hamit (2016-01-01) Temperature dependence of the dielelctric constant epsilon(a) along a axis and the spontaneous polarization P-S is analyzed near the ferroelectric transition (T-C = 182 degrees C) in K2CoCl4. The power-law formula is used for the analysis of the observed data from the literature. Critical exponents we determine from our analysis indicate that K2CoCl4 exhibits a weak first order transition. Coercive field EC is also analyzed using the experimental data which decreases smoothly as the temperature increases to...
Calculation of the Spontaneous Polarization and the Dielectric Constant as a Function of Temperature for KH2PO4 Yurtseven, Hasan Hamit (2012-01-01) The temperature dependence of the spontaneous polarization P is calculated in the ferroelectric phase (T < T-C) of KH2PO4 (KDP) at atmospheric pressure (T-C = 122 K). Also, the dielectric constant e is calculated at various temperatures in the paraelectric phase (T > T-C) of KDP at atmospheric pressure. For this calculation of P and epsilon, by fitting the observed Raman frequencies of the soft mode, the microscopic parameters of the pure tunnelling model are obtained. In this model, the proton-lattice inte...
Calculation of the Brillouin frequencies close to phase transitions in NaNO2 Yurtseven, Hasan Hamit (2002-01-01) We calculate here the Brillouin frequencies of the L-mode [010], [001] and [100] of NaNO2 for the phase transitions from the paraelectric phase to the sinusoidal anti-ferroelectric phase near the Neel temperature (T-N = 437.7 K) and to the ferroelectric phase near the critical temperature (T-c = 436.3 K) in this crystalline system. For calculating the frequencies, we use the thermal expansivity data for the phase regions considered, under the assumption that the mode Gruneisen parameter determined for each ...
Calculation of the Dielectric Constant of a Ferroelectric Liquid Crystal From a Mean Field Model YURTSEVEN, HASAN HAMİT; Yurtseven, Hasan Hamit (2011-01-01) The static dielectric constant epsilon(perpendicular to) of the ferroelectric liquid crystal 4-(3-methyl-2-chlorobutanoyloxy)-4'--heptyloxybiphenyl (A7) with high spontaneous polarization is calculated as a function of temperature using a mean field model. This calculation is performed close to the smectic A-isotropic liquid (SmA-I) transition for pure optically active compound (T-c = 81.6 degrees C). For this calculation of epsilon(perpendicular to), the free energy of the SmA phase is expanded in terms of...
Calculation of the Specific Heat Close to Phase Transition in S-triazine KURT, MUSTAFA; Yurtseven, Hasan Hamit (Walter de Gruyter GmbH, 2009-01-01) The specific heat C-V as a function of temperature has been calculated using the quasi-harmonic and mean field approximation for s-triazine close to the transition temperature (T-C=198 K). Using the parameters for the shear strain angle (order parameter) fitted to the observed Raman frequencies of the four bands, the specific heat C-V is calculated from the free energy of s-triazine.
