Description

With the objective of exploring the unknown thermodynamic behavior of LaCo1−xNixO3 family, we present here an investigation of the temperature-dependent (10K ≤ T ≤ 300K) thermodynamic properties of LaCo1−xNixO3 (x=0.1, 0.3, 0.5). The specific heat of LaCoO3 with Ni doping in the perovskite structure at B-site has been studied by means of a Modified Rigid Ion Model (MRIM). This replacement introduces large cation variance at B-site hence the specific heat increases appreciably. We report here probably for the first time the cohesive energy, Reststrahlen frequency (υ) and Debye temperature (θD) of LaCo1−xNixO3 compounds
