Magnetic and electronic properties in CeTSi3 and CeTGe3 (T: transition metal)
Abstract
We investigated the magnetic properties of CeTSi3 (T: Ru, Os, Co, Rh, Ir, Pd and Pt) and CeTGe3 (T: Co, Rh and Ir) by measuring their electrical resistivity and magnetic susceptibility. CeRuSi3, CeOsSi3 and CeCoSi3 do not order magnetically, with a large Kondo temperature of about 200 K. The other compounds order antiferromagnetically, and are very similar to each other in their magnetic and electronic properties, which is related to a large crystalline electric field (CEF) splitting energy of the 4f electron, about 500 K in CeIrSi3.
