The ternary system Tm–Ni–In at 870 K

Abstract

Abstract The isothermal section of the Tm–Ni–In system at T = 870 K was constructed. Nine ternary compounds: Tm 10 Ni 9 In 20 , TmNi 1–0.60 In 1–1.40 , Tm 2 Ni 2 In, Tm 2 Ni 1.78 In, Tm 5 Ni 2 In 4 , Tm 11 Ni 4 In 9 , Tm 4.83 Ni 2 In 1.17 , Tm 6 Ni 2 In and Tm 14 Ni 3 In 3 exist in the system at the temperature of investigation. Solid solutions with In/Ni and Tm/In mixing were noticed for numerous compounds. A broad substitution of Ni for In was observed for TmNi 1–0.60 In 1–1.40 , and of Tm for In for the TmNi 2 –TmNi 4 In section. An interstitial solid solution Tm x NiIn, based on binary equiatomic NiIn, extends up to 8 at.% Tm ( x = 0.17). The magnetic properties of TmNiIn, Tm 2 Ni 2 In and Tm 5 Ni 2 In 4 are also reviewed.
