A series of CdNCo{sub 3-z}Ni{sub z} (0{<=}z{<=}3) samples were prepared from CdO and metal powders under NH{sub 3} atmosphere at 743 K. The structural and physical properties were investigated by means of X-ray powder diffraction, temperature dependent resistivity and magnetic measurements. X-ray powder diffraction results show that CdNCo{sub 3} is a new ternary nitride with antiperovskite structure, and it can form a complete solid solution series with CdNNi{sub 3}. Both CdNCo{sub 3} and CdNNi{sub 3} samples show metallic temperature dependent resistivity and exhibit a Fermi liquid behavior below 50 K. All samples are ferromagnetic, and their coercivity and remanence decrease as the Ni content increases. The temperature dependence of the magnetization of the CdNCo{sub 3-z}Ni{sub z} samples can be well fitted to the combination of a Bloch term and a Curie-Weiss term. The CdNCo{sub 3} sample is ferromagnet with coercivity of 240 Oe at room-temperature. In contrast to the paramagnetism previously reported, our CdNNi{sub 3} sample exhibits very soft and weak ferromagnetism. - Graphical Abstract: CdNCo{sub 3} is a new ternary nitride with antiperovskite structure, and it can form a complete solid solution series with CdNNi{sub 3}. Highlights: > CdNCo{sub 3-z}Ni{sub z} (0{<=}z{<=}3) samples were synthesized by solid-gas reactions. > CdNCo{sub 3} is a new ternary antiperovskite nitride, and it can form a complete solid solution series with CdNNi{sub 3}. > Both CdNCo{sub 3} and CdNNi{sub 3} samples show metallic behavior and exhibit a Fermi liquid behavior below 50 K. > Magnetic measurements show that CdNCo{sub 3} and CdNNi{sub 3} exhibit ferromagnetic and weak ferromagnetic behavior, respectively.
