Contribution a l'etude des systemes NiSb et CoNiSb par diffraction-X

Supplementary measurements of the primary crystalline phases of the Co–Ni–Sb and the Co–Fe–Sb ternary systems

“…As for the Co-Ni-Sb system, Dudkin and Abrikosov [15] and Naud and Parijs [16] reported the partial isothermal sections in the range of about 50-100 at.%Sb at 813 K and 873 K respectively. Five single phase regions, , 1 , 2 , Á and Sb, seven two-phase regions, Sb + Á, Sb + 2 , Á + 1 , Á + 2 , + 1 , + Á and + 2 , and three three-phase regions, Sb + Á + 2 , Á + + 1 and Á + + 2 were indicated.…”

Low-temperature physical properties and electronic structures of Ni 3 Sb, Ni 5 Sb 2 , NiSb 2 , and NiSb

“…[18,19] The Ni 3 Sb, NiSb, and NiSb 2 phases crystallize with the well-known Cu 3 Ti, NiAs, and FeS 2 type structure respectively, whereas Ni 5 Sb 2 crystallizes in a unique type of structure. [20][21][22] There is very scarce information in the literature about their low-temperature physical properties. The high-temperature phase of Ni 3 Sb attracted a great deal of attention, because Ni atoms of this alloy possess the highest mobility ever observed in a metallic system.…”

Unusually high vacancy concentrations in

“…Although its existence was never doubted, the actual structure of this phase is highly controversial: first x-ray diffraction studies (Fürst andHalla 1938, Osawa andShibata 1940) gave a tetragonal structure, which was refuted by Schubert (1956) who claimed a cubic (DO 3 ) phase. Panteleimonov et al (cited by Shunk 1969) found a hexagonal cell, whereas Naud and Parijs (1972) reconfirmed Fürst and Halla's findings.…”

“…(1) There is no doubt that the structure is cubic. The claims of a tetragonal (Fürst and Halla 1938, Osawa and Shibata 1940, Naud and Parijs 1972 or a hexagonal phase (Panteleimonov et al, cited by Shunk 1969) cannot be confirmed. The peak positions correspond to those expected for a DO 3 -ordered cubic structure.…”
