Аннотация: The Tb-Co-In system at 870 K has been investigated by X-ray powder diffraction and microprobe elemental analyses. The existence of the known compounds TbCo2In (PrCo2Ga-type), Tb2CoIn8 (Ho2CoGa8-type), Tb11Co4In9 (Nd11Pd4In9-type), Tb23Co7In20 (Er23Co6.7In20.3-type), Tb6Co2In (Ho6Co2Ga-type) and Tb14Co3In3 (Gd14Co3In2.7-type) has been confirmed and novel Sm26Co11Ga6-type Tb26Co5-6In12-11 (space group P4/mbm, N 127, tP86), ~Tb18Co67In15, ~Tb5Co3In2 (unknown structure) and qusibinary PuNi3-type Tb1-0.74Co3In0-0.26 have been detected in the Tb-Co-In system at 870 K. The appreciable solubility of other binaries was no observed in the Tb-Co-In system. The Ho2CoGa8-type Tb2CoIn8 shows antiferromagnetic ordering at TN = 32 K with field-sensitive paramagnetic state and the Sm26Co11Ga6-type Tb26Co5In12 exhibits the Curie temperature (TC) at 72 K. The Er23Co6.7In20.3-type Tb23Co7In20 ferromagnet with TC = 56 K and Tm ~ 28 K in a field of 10 kOe and it shows hard magnetic properties at low temperatures. The Ho6Co2Ga-type Tb6Co2In shows field-sensitive ferro-antiferromagnetic ordering below 75 K.
