Abstract

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 (Er₂₃Co_6.7In_20.3-type), Tb₆Co₂In (Ho₆Co₂Ga-type) and Tb₁₄Co₃In₃ (Gd₁₄Co₃In_2.7-type) has been confirmed and novel Sm₂₆Co₁₁Ga₆-type Tb₂₆Co₅–₆In_12-11 (space group P4/mbm, N 127, tP86), ∼Tb₁₈Co₆₇In₁₅, ∼Tb₅Co₃In₂ (unknown structure) and qusibinary PuNi₃-type Tb_1-0.74Co₃In_0-0.26 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 T_N = 32 K with field-sensitive paramagnetic state and the Sm₂₆Co₁₁Ga₆-type Tb₂₆Co₅In₁₂ exhibits the Curie temperature (T_C) at 72 K. The Er₂₃Co_6.7In_20.3-type Tb₂₃Co₇In₂₀ ferromagnet with T_C = 56 K and T_m ∼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.
