- Аннотация: The Tb-Co-Ga system has been investigated at 870 K by X-ray powder and microprobe elemental analyses. The existence of the known compounds TbGo5Ga7 (ScFe6Ga6-type), Tb2Co3Ga9 (Y2Co3Ga9-type), TbCoGa5 (HoCoGa5-type), Tb6Co7Ga21 (Ho6Co7Ga21-type), Tb4Co3Ga16 (Sm4Co3Ga16-type), Tb2CoGa8 (Ho2FeGa8-type), TbCo3~2.8Ga2~2.2 (HoNi2.6Ga2.4-type), Tb3Co7~5.4Ga2~3.6 (CeNi3-type), TbCo1~1.67Ga1~0.33 (TiNiSi-type), Tb2CoGa3 (Lu2CoGa3-type), Tb3Co3Ga (W3CoB3-type), Tb2Co2Ga (Mo2NiB2-type) and Tb6Co2~2.2Ga1~0.8 (Ho6Co2Ga-type) has been confirmed, the TbCo6.7-5.5Ga0.3-1.5 (TbCu7-type) is suggested, meanwhile new MgZn2-type TbCo1.33Ga0.67, Er12Ni5Ga3-type Tb12Co5~5.5Ga3~2.5 and Sm26Co11Ga6-type Tb26Co5~9.4Ga12~7.6 were detected at 870 K. Quasi-binary solid solutions were detected for Tb2Co17, TbCo5, Tb2Co7, TbCo3, TbCo2, TbGa2 and Tb5Ga3 at 870, while no appreciable solubility was observed for the other binary compounds in the Tb-Co-Ga system. Magnetic properties of the Tb4Co3Ga16, Tb2CoGa3, Tb3Co7Ga2, Tb3Co8Ga and Tb26Co9.4Ga7.6 compounds have been studied this work. Tb4Co3Ga16 is antiferromagnetic, while Tb2CoGa3, Tb3Co7Ga2, Tb3Co8Ga and Tb26Co9.4Ga7.6 exhibit mixed ferro-antiferromagnetic ordering. Additionally, new Er12Ni5Ga3-type {Dy, Ho}12Co5.5Ga2.5, Sm26Co11Ga6-type Gd26Co9.2Ga7.8, Dy26Co8Ga9, Er26Co5Ga12 compounds and Cr5Ga3-type Dy5Co0.9Ga2.1 quasi-binary solid solution have been detected in this work.
