Crystal Growth, Structure, Magnetic, and Transport Properties of TbRhIn₅

Abstract

Single crystals of TbRhIn5 were synthesized using the flux growth method. TbRhIn5 adopts the HoCoGa5 structure type and crystallizes in the space group P4/mmm, Z = 1. Lattice parameters are a = 4.6000(6) A, c = 7.4370(11) A, and V = 157.29(6) A3. Transport measurements show that TbRhIn5 is metallic (drho/dT > 0). A sharp antiferromagnetic transition is observed at T(N) = 48 K in the susceptibility data for TbRhIn5, which is highly anisotropic when the field is oriented along the c axis and a-b plane of the crystal and has an average effective moment of 9.72 muB/Tb3+.

New compounds and structures in the solid state

“…The compound TbRhIn 5 has been studied 62 as an analogue of the heavy fermion phase CeRhIn 5 which shows an unusual combination of magnetic order and superconductivity. TbRhIn 5 adopts the HoCoGa 5 structure making it isostructural with the Ce analogue and so contains alternating layers of TbIn 3 cuboctahedra with RhIn 2 rectangular.…”
