摘要：

Metallic trigonal BaSi2, which is metastable at atmospheric pressure, was synthesized from semiconductive orthorhombic BaSi2 under high-pressure and high-temperature conditions. Electrical resistivity and DC magnetization measurements down to 2 K showed that trigonal BaSi2 is a superconductor with an onset temperature of 6.8 K.
