原始语种摘要: Novel ternary Laves phase compounds were explored, and Mg2Ir3Si was synthesized via a solid-state reaction. X-ray diffraction studies revealed that Mg2Ir3Si crystallizes in a Mg2Cu3Si-type structure ( P 63/ mmc , D 6 h 4, No. 194), which corresponds to a fully ordered variant of hexagonal Laves phase MgZn2. The structure is composed of a hexagonal diamond network of Mg atoms, a breathing Kagome network of Ir atoms, and a triangular network of Si atoms. Electrical resistivity, magnetization, and specific heat measurements of Mg2Ir3Si revealed that it exhibits superconductivity with a transition temperature of 7 K. This compound is compared to another Laves...
