Abstract

The magnetic structure of the heavy-fermion antiferromagnet Ce₂RhIn₈ is determined using neutron diffraction. It is a collinear antiferromagnet with a magnetic wave vector (1/2,1/2,0) and a staggered moment of 0.55(6)μ_B per Ce at 1.6 K, tilted 38(2)° from the tetragonal c axis. In spite of its layered crystal structure, the phases for the magnetic moments are the same as those in the cubic parent antiferromagnet CeIn₃. This suggests that the cubic CeIn₃ building blocks have a stronger influence on magnetic correlations than intervening RhIn₂ layers, which give the material its apparent two-dimensional lattice structure and renders CeRhIn₅ an incommensurate antiferromagnet.
