- Previous ab initio super-cell calculations of the magnetic properties of the ordered Fe$\text{}_{1-x}$Al$\text{}_{x}$ alloy in the B2 structure are extended to include the disordered state of the alloy and completed with the calculations for ordered and disordered Fe$\text{}_{1-x}$Si$\text{}_{x}$ alloys. The configurations of the Fe atoms in the anti-site (AS) positions of Fe-X super-cell with the antiferromagnetic order were found. The ground state of Fe$\text{}_{1-x}$Al$\text{}_{x}$ with x≃ 0.3 shows the antiferromagnetic order of the Fe-AS magnetic moments. The concentration dependence of the equilibrium lattice parameter and magnetic moment of Fe$\text{}_{1-x}$X$\text{}_{x}$ in the ordered and disordered state differ qualitatively.
