Abstract: We report possible mixed valence behavior in the new ternary compounds CeIr2Ga and YbIr2Ga. These materials crystallize in the hexagonal Na3As structure of space group P6(3)cm. Magnetization, specific heat and transport measurements show reduced magnetic moments and the absence of magnetic order above 0.04K. The quasi-2D structure of these compounds offers the possibility for investigating the role of spatial dimensionality on mixed valence phenomena. (C) 2001 Elsevier Science B.V. All rights reserved.
