Abstract

CePt₂Si crystallizes in the inverse CeNiSi₂-type structure. Magnetic properties are dominated by a mutual interaction of the RKKY
interaction, the Kondo effect and crystalline electric field splitting, resulting in long range magnetic order below about 7 K. A slightly enhanced Sommerfeld value γ = 42 mJ /mol K² and a distinct temperature dependence of the electrical resistivity refers to Kondo interaction in presence of strong crystalline electric field splitting.
