Structural, magnetic and valence properties of CeM2Sn2 (M = Ni, Cu, Rh, Pd, Ir, Pt)

Abstract We report on new Sn-based compounds belonging to the tetragonal CaBe 2 Ge 2 (CA) structure. In all the studied compounds, Ce is trivalent without magnetic order appearance at 4.2 K. Thesresults can be understood on the basis of the Doniach model, previously used for Si and Ge based materials.
