摘要：

The development of magnetic correlations at low temperatures was studied by muon spin relaxation (mu SR) and specific heat measurements in CePtxNi1-xSn (x = 0.12, 0.2) and CeCuxNi1-xSn (x = 0.05, 0.1, 0.2). Doping with Pt up to 20% increases the magnetic correlations only weakly. In contrast, doping with either 10% or 20% Cu strengthens the correlations up to the point of forming a spin-glass-like state and finally long range order. The large difference in magnetic behavior between CePtxNi1-xSn and CeCuxNi1-xSn shows that the increase in d electron density when doping with Cu is likely to be the important factor for strengthening magnetism.
