Although the vast majority of high-T c cuprate superconductors are hole-doped, a small
family of electron-doped compounds exists. Underinvestigated until recently, there has been …

An understanding of the high-temperature copper oxide (cuprate) superconductors has
eluded the physics community for over thirty years and represents one of the greatest …

In the hole-doped cuprates, a small number of carriers suppresses antiferromagnetism and
induces superconductivity. In the electron-doped cuprates, on the other hand …

accepted August 17, 2006; published November 10, 2006) Mechanisms of Mott transitions
and dx2Āy2-wave superconductivity (SC) are studied in the half-filledband Hubbard model …

Many important questions for high-T c cuprates are closely related to the insulating nature of
parent compounds. While there has been intensive discussion on this issue, all arguments …

A review of the phenomenology and microscopy of cuprate superconductors is presented,
with particular attention to universal conductance features, which reveal the existence of two …

To decipher the mechanism of high-temperature superconductivity, it is important to know
how the superconducting pairing emerges from the unusual normal states of cuprate …

We investigated the generic phase diagram of the electron doped superconductor, Nd2−
xCexCuO4, using films prepared by metal organic decomposition. After careful oxygen …

The superconductivity phase diagrams of electron-doped cuprates of the form R 2− x Ce x
Cu O 4 (with R= La, Pr, Nd, Sm, and Eu) have been determined for cerium compositions 0< …

We have successfully synthesized La 1.8-x Eu 0.2 Sr x CuO 4 (x= 0 and 0.05) with the Nd 2
CuO 4-type (T'-type) structure by means of the structural transformation at low temperatures …
