We calculate the temperature dependence of the infrared frequencies of the TO and LO modes with the symmetries of A(1), B-1 and B-2 mainly in the ferroelectric phase of NaNO2. This calculation is carried out using the volume dependence of the infrared frequencies through the mode Gruneisen parameter in this crystal. The volume dependences of the infrared frequencies are fitted to the observed frequencies by using constant mode Gruneisen parameter in the ferroelectric phase of NaNO2. Our results show that this method of calculating the infrared frequencies describes the observed behaviour of NaNO2 adequately.

Calculation of the Raman frequency and the damping constant of a coupled mode in the ferroelectric and paraelectric phases in KH(2)PO(4) KARACALİ, HUSEYİN; Kiraci, A.; Yurtseven, Hasan Hamit (Wiley, 2010-04-01) The Raman frequency of the coupled mode omega_ associated with the order parameter is calculated as a function of pressure from the mean field theory in the ferroelecric phase of KDP. Using the frequencies of the coupled mode, the pressure dependence of the damping constant Gamma_ is calculated by the proton spin lattice relaxation time and by the energy fluctuation of this mode of KDP in the ferroelectric (FE) phase. For the paraelectric (PE) phase, the Raman frequency of the coupled mode omega is calculat...
Order-disorder transition in the ferroelectric LiTaO3 KİRACI, ALİ; Yurtseven, Hasan Hamit (Informa UK Limited, 2019-10-26) The temperature dependences of the damping constant and the relaxation time are calculated by using the Raman frequencies of a* and the lowest A(1) (TO) phonons in the ferroelectric phase close to the ferroelectric-paraelectric transition in LiTaO3 (T-C = 963 K). Both calculations are performed by considering the frequency as an order parameter for the pseudospin-phonon (PS) and the energy fluctuation (EF) models using the observed data from the literature. Values of the activation energies of this crystal ...
Calculation of the Raman frequency shifts for the alpha phase of solid oxygen Yurtseven, Hasan Hamit (Elsevier BV, 2017-01-01) We calculate in this study the Raman frequencies of the two librons and one vibron at various pressures at constant temperatures of 10 K and also at the temperatures of 6 and 18 K by using the volume data from the literature through the mode Gruneisen parameter for the a phase of oxygen.
Analysis of the Spontaneous Polarization and the Dielectric Constant Near the Ferroelectric Phase Transition in TSCC Yurtseven, Hasan Hamit (Informa UK Limited, 2008-01-01) The temperature dependence of the spontaneous polarization and the dielectric constant has been analyzed for the fixed pressures of 0.001,1 and 2.2 kbar close to the phase transitions in TSCC. This analysis is performed using the experimental data for TSCC according to a power-law formula. From our analysis, using the experimental data for the spontaneous polarization, we deduce the values of the critical exponent = 0.32 (1 bar), 0.28 (1 kbar) and 0.26 (2.2 kbar) for the spontaneous polarization near the tr...
Critical behaviour of the polarization, tilt angle, electric susceptibility and the specific heat close to the SmA-ferroelectric SmC (SmC*) phase transitions Yurtseven, Hasan Hamit; Kilit, E. (Informa UK Limited, 2006-01-01) This study gives the temperature dependence of the two order parameters, namely, polarization P and the tilt angle theta, when there is a biquadratic coupling P-2 theta(2) in the expansion of the Landau free energy. This applies to the electric-field-induced SmA-Ferro-Electric SmC (SmC*) phase transition. From this expansion of the Landau free energy in terms of the polarization and the tilt angle, we obtain the temperature dependence of the electric susceptibility chi and the electric field dependence of t...
