Magnetic field controlled charge density wave coupling in underdoped YBa2Cu3O6+x
Abstract
The interplay between competing orders in high-temperature superconductors can be tuned by the application of magnetic fields. Here, Chang et al. report high field induced three-dimensional charge density wave in underdoped YBa2Cu3O6.67, which suggests Fermi surface reconstruction due to competing orders.
