چکیده انگلیسی
Two novel ternary rare-earth aluminides, CePd3Al2 and LaPd3Al2, were obtained by arc-melting the elements and subsequent annealing at 800 °C. Their crystal structures were determined from the single-crystal X-ray diffraction data. The compounds crystallize with their own structure type: space group Pnma, Z = 4, Pearson symbol oP24, а = 7.491(2) Ã
, b = 4.3575(17) Ã
, â¿Â =Â 13.123(4) Ã
for CePd3Al2 and а = 7.474(7) Ã
, b = 4.3755(17) Ã
, â¿Â =Â 13.323(9) Ã
for LaPd3Al2. The physical behavior of the Ce-based material was studied by means of magnetic, electrical resistivity and heat capacity measurements carried out down to 0.4Â K. The compound was characterized as an antiferromagnetic heavy-fermion system with the Néel temperature TNÂ =Â 1Â K and the Kondo energy scale of about 2Â K.
