Abstract

The compounds CePdSi₂, CeIrSi₂ and CeRhSn₂ have been synthesized and studied by X-ray diffraction, electrical resistivity and magnetic susceptibility. The magnetic susceptibility of CePdSi₂ exhibits two peaks at 6.8 K and 2.5 K, respectively, indicating two antiferromagnetic phase transitions, while that of CeIrSi₂ shows a broad maximum at 150 K, characteristic of valence fluctuating Ce-compounds. CeRhSn₂ remains paramagnetic down to 5 K. The resistivity of CeIrSi₂ exhibits a T² dependence at low temperatures, indicating a Fermi-liquid ground state, while those of CePdSi₂ and CeRhSn₂ shows the presence of Kondo and crystal field effects.
