Ce 2 Pt 3 Si 5 is a Kondo-lattice compound showing an antiferromagnetic transition at T N =6.3 K. We have determined the crystalline electric field (CEF) parameters by using the magnetic susceptibility and magnetization measurements of single-crystalline Ce 2 Pt 3 Si 5 above T N . The obtained CEF parameters explain a Schottky-type anomaly observed in the magnetic part of specific heat. Moreover, we have measured the specific heat and magnetization under various magnetic fields applied along [010] direction to which the magnetic moments are parallel in the ordered state. Above 3 T, we observed extra anomalies in these measurements. This feature can be explained by the competition between the CEF anisotropy and the Ruderman–Kittel–Kasuya–Yosida interaction.
