High-magnetic-field induced charge order in high-T c cuprate superconductors

In the last few years, charge order and its entanglement with superconductivity are under hot debate in high- T c community due to the new progress on charge order in high- T c cuprate superconductors YBa 2 Cu 3 O 6+ x . Here, we will briefly introduce the experimental status of this field and mainly focus on the experimental progress of high-field nuclear magnetic resonance (NMR) study on charge order in YBa 2 Cu 3 O 6+ x . The pioneering high-field NMR work in YBa 2 Cu 3 O 6+ x sets a new stage for studying charge order which has become a ubiquitous phenomenon in high- T c cuprate superconductors.
