“…Then there is a summary decline in the values of the magnetic moments. The same decrease in the magnetic moments on the manganese atoms is recorded in the experiment [16] at gold concentrations in alloys with x  0.6. As defined here, the magnetic moment per Mn atom in these compounds has a maximum value of 4.30 B at x  0.6.…”

“…216) [7,17]. Experimental studies of alloys of mixed atomic composition Pt 1x Au x MnSb [16] did not reveal a significant rearrangement of the symmetry of their crystal lattices. To simplify the calculation procedure in this paper, the positions of the component-atoms of the Pt 1x Au x MnSb alloys (x  0-1) are set using the symmetry operations of a simple cubic lattice P. The correctness of this approach on the example of the study of half-Heusler phases is proved by us in [18,19].…”

“…A spin-polarized version of this method is used to calculate the characteristics of the electronic structure [22]. The parameters a of the cubic lattices of the Pt 1x Au x MnSb alloys (x  0-1) required for the calculations are borrowed from the experimental data, obtained in [16]. The radii (R mt ) of the MT (muffintin)-atomic spheres are chosen from the consideration of minimizing the size of the inter-sphere region in the PtMnSb alloy, which has the smallest unit cell volume.…”

“…From the point of view of zone calculations, a convenient model system of this plan is a series of alloys with the general formula Pt 1x Au x MnSb (x  0-1). The crystal structures and magnetic properties of Pt 1x Au x MnSb compounds are studied using Xray diffraction and magnetometry in [16]. Here, it is found that the lattice parameters of these compounds increase with increasing Au concentration.…”

Using zone calculations in the FLAPW (the full-potential linearized augmented-plane-waves) model, the information on the energy, charge and spin characteristics of Pt 1x Au x MnSb (x  0-1) alloys is obtained. As established, the interatomic spatial electron density decreases, covalent bonds weaken, and the cohesive energies of the alloys decrease with an increase in the concentration of Au atoms in Pt 1x Au x MnSb alloys. As found, the dominant contribution to the formation of magnetic moments in Pt 1x Au x MnSb alloys is made by the 3d electrons of manganese atoms. In alloys with x  0.25 and x  0.5, the total polarization of Fermi electrons is registered, which converts these alloys to the half-metallic state.

“…The sequential transition of PtMnSb → NiMnSb was studied in [10,11] using the system of solid solutions Pt1−xNixMnSb alloys (x = 0.0-1.0). It is established here that this transition does not lead to a change in the symmetry of the crystal lattices of solutions.…”

Using zone calculations in the FLAPW (the full-potential linearized augmented-plane-waves) model, information on the energy, charge and spin characteristics of Pt1−xNixMnSb alloys (x = 0.0-1.0) is obtained. As established, with an increase in the concentration of nickel atoms in Pt1−xNixMnSb alloys, the interatomic space density of electrons decreases, covalent bonds weaken, and the cohesive energies of the alloys decrease. The dominant contributions to the formation of magnetic moments in Pt1−xNixMnSb alloys are provided by 3d electrons of manganese atoms. In alloys with х ≥ 0.50, a complete polarization of Fermi electrons is registered that converts these alloys to a half-metallic state.
