- The magnetic ordering of the $Tb_2Ni_{1.78}In$ and $Tb_2Ni_2In$ have been studied by neutron diffraction measurements. $Tb_2Ni_{1.78}In$ with the tetragonal $Mo_2FeB_2$-type (space group P4/mbm, tP10) is antiferromagnet with the Néel temperature equal to 20 K. Below this temperature Tb moments form collinear magnetic structure commensurate with the crystal, described by the propagation vectors equal to (1/4, 1/4, 1/2). Magnetic moment equal to 7.60(6) $μ_{B}$ is parallel to c-axis. The Tb_2Ni_2In in the orthorhombic $Mn_2$ $lB_2$-type (space group Cmmm, oC10) was detected as an impurity in the studied sample. It orders antiferromagnetically below ≈ 100 K with collinear moment arrangement described by the propagation vector (1/2, 1/2, 1/2). t 1.6 K $μ_{Tb}$ = 6.33(14) $μ_{B}$ and is parallel to the c-axis.
