• Ab-initio study of the electronic properties of Rh2MnZ (Z=Ge, Sn, Pb).
• Thermodynamic properties of Rh2MnZ (Z=Ge, Sn and Pb) are predicted.
• Pressure effect on the structural and electronic properties.
• The effect of temperature and pressure on the Debye temperature.
We have investigated the electronic structure, magnetic and thermal properties of the ternary full-Heusler alloys Rh2MnZ (Z=Ge, Sn, Pb) under pressure employing the full potential linearized augmented plane wave (FP-LAPW) plus local orbitals method based on the density functional theory (DFT), For the exchange–correlation effects we have adopted the generalized gradient approximation (GGA).Through the quasi-harmonic Debye model, we also study the thermodynamic properties of Rh2MnZ (Z=Ge, Sn and Pb). The thermal expansion versus temperature and pressure, the thermodynamic parameters (Debye temperature and specific heat) with pressure P, and the heat capacity at various pressures and temperatures in the ranges of 0 GPa to 0.6 GPa and 0 K to 400 K have been obtained.
