"Thermal and electronic properties of CePd3In2";
Physical Review B,
In this work, we report on the physical properties of orthorhombic CePd3In2 in comparison with isotypic LaPd3In2 (space group Pnma). X-ray powder diffraction Rietveld analysis revealed single-phase composition of both specimens CePd3In2 and LaPd3In2 confirming the CePd3In2 type with space group Pnma. The lattice parameters are a=1.02788(8), b=0.46237(4), and c=0.98765(9) nm for CePd3In2 and a=1.02986(14), b=0.46424(6), and c=0.99498(13) nm for LaPd3In2. Physical properties of CePd3In2 at low temperatures are dominated by a magnetic phase transition into an antiferromagnetic ground state below TN~2.1 K. A mutual interplay of the Kondo effect and the Rudermann-Kittel-Kasuy-Yoshida interaction is responsible for a large Sommerfeld value gamma~500 mJ/mol K2 derived from a model which simultaneously describes the Kondo effect and long-range magnetic order.
