摘要：

Single crystals of TbPdBi, a representative of the group of half-Heusler bismuthides, were studied by means of magnetic susceptibility, heat capacity, electrical resistivity, magnetostriction and thermal expansion measurements. The compound was characterized as an antiferromagnet with the Neel temperature T-N approximate to 5.3 K. Neutron diffraction experiment confirmed the antiferromagnetic ordering and yielded the propagation vector k = (1/2, 1/2, 1/2). Remarkably, this k vector is in accord with the recently developed theory of antiferromagnetic topological insulators.
