摘要
The ternary compounds Yb2T2In (T = Cu, Pd and Au) have been synthesized. The indides Yb2Au2In and Yb2Pd2In crystallize in the Mo2FeB2 structure type, while Yb2Cu2In proved to be isotypic with the W2CoB2 structure. Magnetic, resistivity and specific heat measurements revealed no magnetic order for any of the compounds but, while in Yb2Cu2In and Yb2Au2. In the valence of Yb was observed to be nu = 2, Yb2Pd2In exhibits intermediate valence behavior. (C) 2001 Elsevier Science Ltd. All rights reserved.
