NMR study of topological superconductor

用核磁共振方法研究了拓扑超导体CuxBi2Se3的有力候选者。获得了~(63)Cu、~(209)Bi、~(77)Se的核磁共振信号。核磁共振研究表明Bi2Se_3层是导电层。~(125)Te核磁共振研究揭示了具有强自旋轨道耦合的新型超导材料IR1-xPtxTe2的超导转变。接下来，我们聚焦了量子自旋液体相附近的超导电性。通过对有机混晶Et2Me2As1-xSbx[Pd(Dmit)2]2的加压电阻率测量，成功地观察到了其超导电性。

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.
