The evolution of magnetism and superconductivity in Ce2Rh1-xPdxIn8 solid solutions has been studied within the entire concentration range by means of thermodynamic and magnetic measurements at ambient pressure and at temperatures between 0.35 K and room temperature. For this purpose, single crystals with Pd concentrations x=0, 0.10, 0.15, 0.30, 0.45, 0.55, 0.85 and 1 have been grown from In self-flux and characterized by x-ray diffraction and microprobe analysis.
Starting from the antiferromagnet Ce2RhIn8, the Neel temperature gradually decreases with increasing Pd concentration and the antiferromagnetism has disappeared for x }= 0.45. Superconductivity has been observed only for Ce2PdIn5.
