Influence of temperature on thermal properties of (Sm, Eu) VO3
Source abstract
Abstract
Abstract The bulk modulus and thermal properties of orthovanadates SmVO3 and EuVO3 in the temperature range 5 K≤T≤300 K have been investigated using the Modified Rigid Ion Model (MRIM) by incorporating the effect of lattice distortions. The results on the specific heat, cohesive energy, molecular force constant, the reststrahlen frequency and the Gruneisen parameter following the temperature driven structural phase transitions are presented. Our results are in fair agreement with the available experimental data. The specific heat results can further be improved by including the spin and orbital ordering contributions to the specific heat.
