Temperature dependence of magnetic and thermal properties of chiral HyFe and HyMn close to phase transitions by using the Landau mean field model
(Elsevier Science, 2019)
Magnetic and thermal properties of chiral metal formate frameworks (MOFs) of NH2NH3M(HCOO)(3), M = Fe, Mn, namely, HyFe and HyMn are investigated close to phase transitions by using Landau phenomenological model. By expanding ...
Analysis of vibrational spectra in relation to the thermodynamic quantities close to the phase transitions in ammonium halides (NH4F and NH4I)
(Elsevier, 2017)
The pressure dependences of the vibrational frequencies of the TO and L modes are analyzed from the literature data and the thermodynamic quantities such as isothermal compressibility K gamma, thermal expansion alpha p and ...
Calculation of the thermodynamic quantities of perovskite metal organics DMAKCr and perovskite HyFe close to the weakly first-order relaxor-like structural transformation using the mean field theory
(World Scientific Pub., 2019-04-30)
Weakly first-order or nearly second-order phase transitions occurring in metal{organic frameworks (MOFs), particularly in DMAKCr and perovskite HyFe, are studied under the mean field model by using the observed data from ...
Magnetic Transitions in Two Novel Mixed-Valence Iron(Ii)–Iron(Iii) Metal Formate Frameworks : Two Sublattice Model
(Elsevier B.V., 2022)
We study the two-sublattice model in the mean field theory by expanding the Gibbs free energy in terms of the magnetizations M1 (Mup) and M2 (Mdown) with the quadratic coupling M12M22 (quadrupolar interactions) for the ...
Raman frequencies calculated at various pressures in phase I of benzene

We calculate in this study the pressure dependence of the frequencies for the Raman modes of A (Ag), B (Ag, B2g) and C (B1g, B3g) at constant temperatures of 274 and 294K (room temperature) for the solid phase I of benzene. ...
Calculation of the Raman frequencies as a function of pressure in the solid phases II and III (III’) of benzene
(Springer, 2013)
We calculate here the Raman frequencies of the lattice modes A(Ag), B(B2g) and C(B1gB3g) as a function of pressure at room temperature for the solid phases (II, III and III’) of benzene. This calculation is performed using ...
