Understanding cuprate superconductors requires better knowledge of the microscopic structure of their charge-density waves (CDW). Here, the authors report evidence that the long-range CDW order in YBa2Cu3Oy has a local commensurate period of three un

In order to identify the mechanism responsible for the formation of charge-density waves (CDW) in cuprate superconductors, it is important to understand which aspects of the CDW’s microscopic structure are generic and which are material-dependent.

High-$T_{\rm{c}}$ cuprate superconductors host spin, charge and lattice instabilities. In particular, in the antiferromagnetic glass phase, over a large doping range, lanthanum based cuprates display a glass-like spin freezing with antiferromagnetic

The nature of the pseudogap phase of hole-doped cuprate superconductors is still not understood fully. Several experiments have suggested that this phase ends at a critical hole doping level p*, but the nature of the ground state for lower doping is

We present a detailed study of the temperature ($T$) and magnetic field ($H$) dependence of the electronic density of states (DOS) at the Fermi level, as deduced from specific heat and Knight shift measurements in underdoped ${\mathrm{YBa}}_{2}{\math

The upper critical field Hc2 is a fundamental, and technologically important, property that measures the ability of a superconductor to withstand magnetic fields. Recently, there has been a controversy regarding the values Hc2 in high-Tc copper oxide

We report the NMR observation of a skewed distribution of $^{17}\mathrm{O}$ Knight shifts when a magnetic field quenches superconductivity and induces long-range charge-density-wave (CDW) order in ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{y}$

The value of the upper critical field Hc2, a fundamental characteristic of the superconducting state, has been subject to strong controversy in high-Tc copper-oxides. Since the issue has been tackled almost exclusively by macroscopic techniques so fa

We show that $^{63}\mathrm{Cu}$-NMR spectra place strong constraints on both the nature and the concentration of oxygen defects in ortho-II ${\mathrm{YBa}}_{2}{\mathrm{Cu}}_{3}{\mathrm{O}}_{y}$. Systematic deviation from ideal ortho-II order is revea
