NMR study of topological superconductor

采用核磁共振技术对一种强候选拓扑超导体CuxBi2Se3进行了研究。发现63Cu， 209Bi， 77Se核磁共振信号。核磁共振研究表明，Bi2Se3层为导电层。125Te NMR研究揭示了新型超导材料Ir1-xPtxTe2的超导跃迁，该材料具有强自旋-轨道耦合。接下来，聚焦了量子自旋液相附近的超导性。利用压力下电阻率测量方法，成功地观察到了有机混合晶体Et2Me2As1-xSbx[Pd(dmit)2]2的超导性。

A strong candidate of topological superconductor CuxBi2Se3 was studied by NMR. 63Cu, 209Bi, 77Se NMR signals were found. The NMR study indicates that the Bi2Se3 layer is the conducting layer. 125Te NMR study revealed a superconducting transition in a new superconducting material Ir1-xPtxTe2, which has strong spin-orbit coupling. Next, a superconductivity near a quantum spin liquid phase was focused. The superconductivity was successfully observed by resistivity measurement under pressure in organic mixed crystals Et2Me2As1-xSbx[Pd(dmit)2]2.
