Abstract: We report the low temperature magnetic properties of Cd-doped single crystals of Ce2RhIn8 grown from In-flux. Measurements of temperature-dependent magnetic susceptibility, heat capacity, electrical resistivity and X-ray magnetic scattering revealed that Cd-doping enhances the antiferromagnetic ordering temperature from T-N = 2.8 to 4.8 K for crystals with nominal Cd-concentration of similar to 20%. Similarly to the pure compound, Cd-doped Ce2RhIn8 presents just below TN a commensurate anti ferro magnetic structure with a propagation vector (eta) over right arrow = (1/2, 1/2, 0). Comparisons between our results and the general effects of Cd-doping on the single layer related family CeMIn5 (M = Co, Rh and Ir) will also be given. (C) 2009 Elsevier B.V. All rights reserved.
