According to foreign media reports, the research team of the Japanese Material Research Institute recently synthesized a new superconducting compound containing gold and silicon. The research team produced a new type of superconductor named "SrAuSi3" under the conditions of 1500 ° C and 60,000 standard atmospheric pressures, causing gold to react with silicon and strontium disilicide. . After theoretical calculation and analysis, the electronic structure of the new superconductor is higher than that of the gold element with a larger atomic number, the electron number is increased, and the electron magnetic and spin-orbit coupling are stronger. It belongs to the BaNiSn3 structure compound. The research results have been published in "Material Chemistry" edited by the American Chemical Society.
