Abstract
We report the synthesis, from an indium flux, of single crystals of EuCu2Si 2. In contrast to previous studies of polycrystalline samples in which inte rmediate-valent behavior for Eu is reported, we find that in single crystal s of EuCu2Si2 the behavior of Eu is divalent, including the presence of ant iferromagnetic order at 10 K. The origins of these variations in ground-sta te properties are discussed in terms of effective chemical pressure and loc al changes in chemical environment.
