Evolution of magnetism in Pd-substituted Ce${}_2$RhIn${}_8$ single crystals

Abstract

The evolution of magnetism and superconductivity in Ce${}_2$Rh${}_{1-x}$Pd${}_x$In${}_8$ 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 Ce${}_2$RhIn${}_8$, the Néel temperature gradually decreases with increasing Pd concentration and the antiferromagnetism has disappeared for $x\ge 0.45$. Superconductivity has been observed only for Ce${}_2$PdIn${}_8$.
