Magneto-electronic, mechanical and thermodynamic properties of full-Heusler alloys Cr2GdGe1-xSnx

In this work we have used the density functional theory (DFT) to investigate the ground state properties, mechanical and magneto-electronic properties of the quaternary full-Heusler alloys Cr2GdGe1-xSnx in L21 structure. The system are treated in ferromagnetic order. The electronic structure report that, our compounds have half-metallic (HM) nature. The mechanical results show that these compounds are mechanically stable. The thermodynamic stability of these compounds are also determined. In addition the temperature and pressure effects on the bulk modulus, heat capacities, Debye temperatures and entropy are computed and discussed in details.
