Crystal structure and properties of the new ternary YbZnxGa4−x and Yb3Zn11−xGax phases

Crystal structures of three new ternary YbZnxGa4−x (0.25 ≤ x ≤ 0.5 and 0.75 ≤ x ≤ 2) and Yb3Zn11−xGax (3.5 ≤ x ≤ 4.2) phases have been determined by means of single crystal X-ray as well as powder diffraction. They crystallize in known structure types, namely: CaCu0.15Ga3.75, BaAl4 and La3Al11. Magnetic and transport properties were investigated for the new YbZnxGa4−x compounds. All phases studied show metallic-like and diamagnetic behavior.
