Abstract

Results of magnetoresistivity (MR) measurements on selected members of the ( Ce_{1 - x} Gd_x ) Pt₂ Si₂ system down to low temperatures in fields up to 8 T are presented. The MR is negative and is related to the temperature-dependent susceptibility. Single-ion Kondo-like behaviour is observed at higher temperatures. At lower temperature ( T {less-than or slanted equal to} 13 K) an inflection point develops in the MR curves with a tendency to saturation towards high fields. The results are interpreted in terms of the Friedel-de Gennes model.
