摘要：
Specific heat and Bulk modulus (B) of new perovskite-type cobaltates Pr1-xNdxCoO3 has been studied by means of a Modified Rigid Ion Model (MRIM) and Atoms in Molecules (AIM) theory in a wide temperature range (1K <= T <= 1000K). The effect of Nd doping on the elastic, cohesive and thermal properties of PrCoO3 have been studied probably for the first time by an atomistic approach. The computed results are in good agreement with the available experimental data.
