摘要：

We report on magnetisation, resistivity and specific heat measurements of R2Pd2In compounds synthesised with the nominal composition R40Pd41In19 (R=La, Ce, Pr, Nd, Sm, Gd, Tb, Dy, Ho, Er, Tm, Yb, Lu and Y), Magnetic and thermodynamic measurements reveal antiferromagnetic order below 32 K for this series except for Y, La, Yb and Lu. An appreciably wide homogeneity range is found for Ce2Pd2+xIn1-x where ferro- or antiferromagnetic order or both occur with typical features of a Kondo lattice. Yb2Pd2In exhibits intermediate valent behaviour and no magnetic order could be detected down to 0.3 K. (C) 1998 Elsevier Science S.A. All rights reserved.
