Abstract

Single crystals of the ternary Yb_0.5Co₃Ge₃ have been grown out of molten Sn flux and characterized by single crystal and synchrotron powder X-ray diffraction. Yb_0.5Co₃Ge₃ adopts a hybrid YCo₆Ge₆/CoSn structure, crystallizing in the hexagonal space group P6/mmm with lattice parameters α ≈ 5.1 Å and c ≈ 3.9 Å. Although the compound does not magnetically order down to 2 K, Weiss temperatures of -21 K, -18.7 K, and -21 K for H//α, H//c, and the polycrystalline average, respectively, indicate antiferromagnetic interactions with μ_eff = 4.23 μB, slightly lower than the full Yb³⁺ moment of 4.54 μB. Field-dependent magnetization up to 7 T measured at 2, 5, and 10 K show a linear dependence along H//α. Magnetization at 2 K for H//c approaches saturation near 1 μB, lower than the full Yb³⁺ moment. Herein, we present the synthesis and characterization of Yb_0.5Co₃Ge₃.
