The discovery of high-temperature superconductivity in the copper oxides in 1986 triggered
a huge amount of innovative scientific inquiry. In the almost three decades since, much has …

Underdoped high-Tc superconductors are frequently characterised by a temperature, T*,
below which the normal-state pseudogap opens. Two different “phase diagrams” based on …

The Van Hove singularity (VHS) provides a paradigm for the study of the role of peaks in the
density of states (dos) on electronic properties. More importantly, it appears to play a major …

This review focuses on the materials chemistry and thermodynamics of the REBa2Cu3O7− x
(RE= rare earth) series of superconductors. The importance of this basic information for …

The thermoelectric power S (T) is studied for Y Ba 2 Cu 3 O 7− δ and Y Ba 2 Cu 4 O 8 as a
function of Zn substitution and hole concentration p. A strong enhancement in S (T) is …

Identifying quantum critical points (QCPs) and their associated fluctuations may hold the key
to unraveling the unusual electronic phenomena observed in cuprate superconductors …

The do** dependence of the ratio of the superconducting condensate density to the
effective mass, nso/m ab*, was studied in detail by muon-spin rotation for Y 0.8 Ca 0.2 Ba 2 …

Many current descriptions of the pseudogap in underdoped cuprates envision a do**-
dependent transition line T*(p) which descends monotonically toward zero just beyond …

Susceptibility and high-resolution 89 Y NMR measurements on 16 O-and 18 O-exchanged
YBa 2 Cu 4 O 8 superconductors show an isotope effect in T c but not in the normal-state …
