“…Ternary lanthanide (Ln) transition-metal (M) aluminide compounds adopting the ThMn 12 structure type have been the subject of intense research efforts for decades as part of a search for materials exhibiting interesting magnetic ground states or transport properties [1,2,[4][5][6]10,11]. These compounds crystallize in the space group I4/mmm with the general formula Ln(M,X) 12 (M¼V-Fe, Ni, Zn; X¼main group element).…”

“…Phase equilibria concerning Al 4 Gd are not known. Recently, a new hexagonal compound Al 17 Gd 2 was found by Pop et al [18] Palasyuk et al [19] measured the electrical resistivity in the temperature range of 1.5 K to 300 K (À271.5°C to 27°C) for Th 2 Zn 17 structure type Gd 2 Fe x Al 17Àx ternary intermetallic compound and refined the cell constants of Gd 2 Fe 10 Al 7 (a = 0.86981 nm and c = 1.26563 nm) and Gd 2 Fe 11 Al 6 (a = 0.86642 nm and c = 1.26164 nm). The crystallization behavior of Al 3 Gd 4 metallic glass has been studied by X-ray diffraction and differential scanning calorimetry.…”

Isothermal section of the Al-V-RE (RE = Gd, Ho) ternary systems at 773 K (500°C) was investigated over the whole concentration range by means of X-ray diffraction and scanning electron microscopy equipped with energy dispersive X-ray analysis. The crystal structures of the Al 43 Mo 4 Ho 6 -type ternary compounds Al 43 V 4 RE 6 were determined with Rietveld refinement method. The intermetallic compound Al 43 V 4 Gd 6 belongs to the Space group P6 3 /mcm, with cell parameters of a = b = 1.0996(6) nm, c = 1.7813(9) nm, a = b = 90 deg, c = 120 deg, and volume of unit cell of 1.8658(9) nm 3 . At 773 K (500°C), all the Al-rich ternary alumides, i.e., reported in the literature were not found. Fifteen and 14 ternary phase fields have been identified in the isothermal section of the Al-V-Gd and Al-V-Ho ternary systems, respectively. The solid solubility of V in Al 2 RE 3 , AlRE, and Al 2 RE amounts to approximately 1.0 at. pct to 2.0 at. pct, whereas the solid solubility of Al in V is approximately 39 at. pct.

“…Thus, the research of ternary compounds or multivariant compounds consisting of the normal metals and the conventional binary compounds received increasing attention, stimulated by the expectation of new compounds with anomalous properties. A notable series of compounds is the ternary intermetallic R-T-M compounds (M ¼ p-electron element), especially the ternary equiatomic intermetallic compounds RMAl (M ¼ Fe, Co and Ni) [6][7][8].…”
