“…Motivated by the unusual thermodynamic behavior and spin dynamics of RVO 3 , we have recently applied modified rigid ion model (MRIM) and successfully explored the elastic and thermodynamic properties of the orthovanadates RVO 3 (R = La, Ce, Pr, Nd, Sm, Eu) and AVO 3 (A = Sr, Pb). [12][13][14] The study of the lattice thermal properties of these compounds may be taken as starting point for the consistent understanding of the more complex physical properties of the rare earth orthovanadates LuVO 3 and ScVO 3 . The essentials of the MRIM formalism and the results obtained from its application are discussed in Sec.…”

We have investigated the elastic, cohesive and thermal properties of (Lu, Sc) VO 3 and Sc 1−x LuxVO 3 (0.6 ≤ x ≤ 0.9) perovskites by means of a modified rigid ion model (MRIM). The variation of specific heat is determined following the temperature driven structural phase transitions. Also, the effect of lattice distortions on the elastic and thermal properties of the present pure and doped vanadates has been studied by an atomistic approach. The calculated bulk modulus (B T ), reststrahlen frequency (ν 0 ), cohesive energy (φ), Debye temperature (θ D ) and Gruneisen parameter (γ) reproduce well with the corresponding experimental data. The specific heat results can further be improved by including the magnetic ordering contributions to the specific heat. Int. J. Mod. Phys. B 2012.26.
