日本国家材料科学研究所(NIMS)的研究人员合成了一种全新超导体SrA uS i3,以金为主要组成元素。以Masaaki Isobe为首的研究团队最近寻找到了一种全新物质,它的晶体结构中缺少空间反转对称构成。该团队成功地利用其合成了一种新型化合物——SrA uS i3,并发现它在绝对零度下展现出了超导性。这种化合物属于一种被称作BaN iS n3型的结构(通式写作AMX3,其中M代表过渡金属元素)。目前,对于空间反转对称破缺超导性的研究主要集中在Rh、Ir和Pt等相对重金属化合物上。但是,利用高压合成方 Researchers at the National Institute of Materials Science (NIMS) have synthesized a new superconductor, SrAuSi3, with gold as its main constituent. A team led by Masaaki Isobe recently looked for a whole new class of materials that lacked space inversion symmetry in its crystal structure. The team succeeded in using it to synthesize a new compound, SrAuSi3, and found it to exhibit superconductivity at absolute zero. This compound belongs to a structure called BaN iS n3 type (general formula AMX3, wherein M represents a transition metal element). At present, the studies on symmetric breaking superconductivity of space inversion mainly focus on the relative heavy metal compounds such as Rh, Ir and Pt. However, the use of high-pressure synthesis side
