Single-phase samples of REAgMg (RE ؍ La, Ce, Eu, Yb) and EuAuMg were prepared by reacting the elements in sealed tantalum tubes in a high-frequency furnace. LaAgMg and CeAgMg adopt the hexagonal ZrNiAl-type structure, while EuAgMg, YbAgMg, and EuAuMg crystallize with the orthorhombic TiNiSi type.
The title compounds were investigated by magnetic susceptibility measurements and 151 Eu Mo¨ssbauer spectroscopy. EuZnIn and EuPtIn show Curie-Weiss behavior above 60 K with experimental magnetic moments of 7.80(5) and 8.0(1) B / Eu, respectively, indicating divalent europium. The zinc compound orde
