Two antiperovskite-type ternary nitrides of InNM{sub 3} (M=Ni, Co) have been synthesized from In{sub 2}O{sub 3} and Ni or Co powders under NH{sub 3} atmosphere at 600 deg. C. InNCo{sub 3} is a new ternary nitride whereas InNNi{sub 3} was previously reported as InN{sub 0.5}Ni{sub 3} with different nitrogen content. The lattice parameters refined by Rietveld method are 3.8445(1) A for InNNi{sub 3} and 3.8541(7) A for InNCo{sub 3}, respectively. Both nitrides show metallic behaviors and below 70 K the T{sup 2} temperature dependence of resistivity was observed indicative of a Fermi liquid behavior. The temperature dependence of the field-cooling (FC) and zero-field-cooling (ZFC) magnetization and time decay of thermoremanent magnetization indicate the spin-glass-like behavior in InNM{sub 3} (M=Ni, Co). The freezing temperatures for this behavior, T{sub f}, are about 300 K for InNNi{sub 3} and 10 K for InNCo{sub 3}, respectively. - Graphical abstract: Two ternary nitrides InNM{sub 3} (M=Ni, Co) were synthesized by solid-gas reactions of metal powders with NH{sub 3}. Both InNNi{sub 3} and InNCo{sub 3} adopt the antiperovskite crystal structure, and measurements of magnetization indicate that they have spin-glass-like properties.
