“…A theoretical study using the full-potential screened Korringa-Kohn-Rotoker method on the Heusler compounds indicated that the total spin moment per unit cell (M t ) scales with Z t ,following the simple Slater-Pauling rule M t = Z t − 24 [2]. Accordingly, the net moment disappears with Z t = 24, and the iron-based members such as Fe 2 VAl, Fe 2 VGa, and Fe 2 TiSn have been found to be nonmagnetic [3][4][5][6][7][8][9], in agreement with the aforementioned Slater-Pauling relation. Such a relation has also been employed to describe the magnetic properties of other Heusler systems [1,2,10,11].…”

The Heusler-type compound of Ru 2 NbGa has been successfully synthesized. X-ray analysis confirms that Ru 2 NbGa crystallizes in a cubic L2 1 structure. The electronic properties of Ru 2 NbGa have been characterized by means of the transport and nuclear magnetic resonance (NMR) measurements. The temperature dependence of the electrical resistivity exhibits a typical semimetallic behavior. The NMR spin-lattice relaxation rate shows activated behavior at higher temperatures, attributing to the thermally excited carriers across a pseudogap. We have also deduced a low Fermi-level density of states (DOS), being consistent with the semimetallic characteristic for Ru 2 NbGa. In addition, we have performed first-principles total-energy calculations including G 0 W 0 and GW 0 corrections for band gaps to investigate the electronic band structure of Ru 2 NbGa. The calculated result reveals an indirect overlap between electron and hole pockets that leads to a residual DOS at the Fermi level, providing a consistent explanation for the experimental observations.

“…It is well established that Fe 2 TiSn alloy belongs to the group of the Heusler-type alloys in which the local atomic disorder induced by formation of anti-site Fe atoms and local disorder profoundly influences the magnetic and electrical transport properties [1]. The existence of the strong chemical disorder was firstly reported by Szytuła et al [2] from the neutron diffraction experiments.…”

“…One major family of these materials is Heusler alloys, 10 which do not have a distinct Fe homoatomic bonding network and whose magnetic order depends on the overall electron count. 11 One member of this family, TiFe 2 Sn, exhibits a hybridization gap, 12 because it fulfills the exact electron count required to be a semiconducting Heusler alloy. R 6 Fe 13 Sn (R = La, Nd, and Pr) adopt a structure with a complex 2D…”

This Article reports two new Hf-rich intermetallics synthesized using Sn flux: Hf 3 Fe 4 Sn 4 and Hf 9 Fe 4-x Sn 10+x. Hf 3 Fe 4 Sn 4 adopts an ordered variant the Hf 3 Cu 8 structure type in orthorhombic space group Pnma with unit cell edges of a = 8.1143(5) Å, b = 8.8466(5) Å, and c = 10.6069(6) Å. Hf 9 Fe 4x Sn 10+x , on the other hand, adopts a new structure type in Cmc2 1 with unit cell edges of a = 5.6458(3) Å, b = 35.796(2) Å, and c = 8.88725(9) Å for x = 0. It exhibits a small amount of phase width in which Sn substitutes on one of the Fe sites. Both structures are fully three-dimensional and are characterized by pseudo one-and two-dimensional networks of Fe-Fe homoatomic bonding. Hf 9 Fe 4-x Sn 10+x exhibits antiferromagnetic order at T N = 46(2) K and its electrical transport behavior indicates that it is a normal metal with phonon-dictated resistivity. Hf 3 Fe 4 Sn 4 is also an antiferromagnet with a rather high ordering temperature of T N = 373(5) K. Single crystal resistivity measurements indicate that Hf 3 Fe 4 Sn 4 behaves as a Fermi liquid at low temperatures, indicating strong electron correlation.
