for different concentrations x (0 ≤ x ≤ 1).
The present result was done by means of DFT calculations. The effect of concentration x on the calculated lattice parameters
and bulk modulus, shows a linear dependence for the lattice parameters with marginal downward bowing parameters equal
to 0.0457 Å, while a nonlinear behavior is observed for the variation of bulk modulus with disorder parameter equal to 4.696
GPa. The estimated elastic constants confirm the mechanical stability of our compounds. The thermodynamic stability was
explored on the basis of the regular solution model. Furthermore, the temperature and pressure effects on the bulk modulus,
heat capacities and Debye temperatures are also computed and discussed in details. The magneto-electronic calculations reveal
that all the presented compounds exhibit a HMF behavior. Finally, we can report that due to the potential half-metallicity
exhibited by our investigated alloys, these compounds could be used for spintronic application.
