Abstract
We report possible mixed valence behavior in the new ternary compounds CeIr 2Ga and YbIr2Ga. These materials crystallize in the hexagonal Na3As structu re of space group P6(3)cm. Magnetization, specific heat and transport measu rements show reduced magnetic moments and the absence of magnetic order abo ve 0.04K. The quasi-2D structure of these compounds offers the possibility for investigating the role of spatial dimensionality on mixed valence pheno mena. (C) 2001 Elsevier Science B.V. All rights reserved.
