Discovery of novel gold-based superconductor

A novel superconductor, SrAuSi3, which contains gold as a principal constituent element has been synthesized by researchers. Up until now, research on superconductivity with broken spatial inversion symmetry has mostly focused on compounds that contain a relatively heavy element M, such as rhodium (Rh), iridium (Ir), and platinum (Pt). However, using a high-pressure synthesis method, the team successfully synthesized for the first time a compound with the same general chemical formula but using gold (Au), which is even heavier, as element M.
