Charge-density-wave order takes over antiferromagnetism in Bi(2)Sr(2−x)La(x)CuO(6) superconductors
Superconductivity appears in the cuprates when a spin order is destroyed, while the role of charge is less known. Recently, charge density wave (CDW) was found below the superconducting dome in YBa(2)Cu(3)O(y) when a high magnetic field is applied perpendicular to the CuO(2) plane, which was suggest...

Sumario: | Superconductivity appears in the cuprates when a spin order is destroyed, while the role of charge is less known. Recently, charge density wave (CDW) was found below the superconducting dome in YBa(2)Cu(3)O(y) when a high magnetic field is applied perpendicular to the CuO(2) plane, which was suggested to arise from incipient CDW in the vortex cores that becomes overlapped. Here by (63)Cu-nuclear magnetic resonance, we report the discovery of CDW induced by an in-plane field, setting in above the dome in single-layered Bi(2)Sr(2−x)La(x)CuO(6). The onset temperature T (CDW) takes over the antiferromagnetic order temperature T (N) beyond a critical doping level at which superconductivity starts to emerge, and scales with the pseudogap temperature T*. These results provide important insights into the relationship between spin order, CDW and the pseudogap, and their connections to high-temperature superconductivity. |
