Order-disorder phase transition of NH4AlF4 through Raman scattering investigations
2014 The low-frequency (0-600 cm1) Raman spectra of NH4AlF4 single crystals (a perovskite-type layer compound) have been studied at different temperatures, and the D184h ~ D134h phase transition occurring around 150 K is evidenced. The Raman data show that it is purely an order-disorder transformation, connected to the reorientational dynamics of the NH+4 ions. A simple model of reorientable ps...
متن کاملA High Pressure Investigation of the Order-Disorder Phase Transition and Accompanying Spin Crossover in [FeL12](ClO4)2 (L1 = 2,6-bis{3-methylpyrazol- 1-yl}-pyrazine)
A high pressure single crystal X-ray diffraction and Raman spectroscopy study has revealed a similar mechanism for both thermal and pressure-induced spin crossover in [FeL12](ClO4)2 (L1 = 2,6-bis{3-methylpyrazol-1-yl}-pyrazine) and the concomitant anion order-disorder transition.
متن کاملCharge ordering phase transition and order - disorder effects in the Raman spectra of NaV
In the ac polarized Raman spectra of NaV 2 O 5 we found anomalous phonon broadening and the energy shift as a function of the temperature, which we relate to the translational symmetry breaking effects caused by the strong electrical disorder due to the fluctuating nature of V 4.5+ valence state of vanadium. The structural correlation length, obtained from comparison between measured and calcul...
متن کاملSpectroscopy, Structural, and Optical Investigations of NiFe2O4 Ferrite
Ni ferrite crystalline material is synthesized using a sol-gel method at two different temperatures. The vibrational and stretching modes, crystalline phase, size distribution and morphology of the products are investigated via Raman back-scattering and Fourier transform infrared (FTIR) spectroscopy, XRD and FESEM, respectively. Vibrational modes of spinel ferrite are observed at Raman and FTIR...
متن کاملEFFECT OF THE NEXT-NEAREST NEIGHBOR INTERACTION ON THE ORDER-DISORDER PHASE TRANSITION
In this work, one and two-dimensional lattices are studied theoretically by a statistical mechanical approach. The nearest and next-nearest neighbor interactions are both taken into account, and the approximate thermodynamic properties of the lattices are calculated. The results of our calculations show that: (1) even though the next-nearest neighbor interaction may have an insignificant ef...
