Reduced Hall carrier density in the overdoped strange metal regime of cuprate superconductors

A study of the high-field Hall coefficient in thallium- and bismuth-based single-layer cuprates demonstrates a smooth evolution of this quantity from p to 1 + p over a wide doping range.

Magnetotransport signatures of antiferromagnetism coexisting with charge order in the trilayer cuprate HgBa₂Ca₂Cu₃O_8+δ

The interplay between superconductivity and competing orders in multi-layered cuprates can shed light on the nature of the superconducting pairing. Here, the authors report on the coexistence of antiferromagnetic and charge orders in different CuO2 planes in a tri-layer cuprate, pointing to a magnetically-mediated mechanism.

Hidden magnetism at the pseudogap critical point of a cuprate superconductor

NMR and ultrasound measurements show that the spin-glass phase exists in a cuprate all the way up to the doping that marks the end of the pseudogap phase. This highlights the possible connection between the pseudogap and Mott physics.
