Pairing symmetry in the cuprate superconductors is an important and controversial topic.
The recent development of phase-sensitive tests, combined with the refinement of several …

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 …

Recent studies on high-T c superconductors have aroused new interest in tunnelling effects
in unconventional superconductors. Unlike in conventional s-wave superconductors, the d …

Understanding the mechanism responsible for superconductivity in the high-temperature
cuprates has been one of the major goals of condensed-matter physicists since the …

This topical review summarizes various features of magnetic penetration depth in
unconventional superconductors. Precise measurements of the penetration depth as a …

This is a revised version of the first edition published in 1991. At the same time, this is a
revised version of the Syokabo edition, which was written in Japanese and published in …

The authors present a review of recent muon spin rotation (μSR) studies of the vortex state in
type-II superconductors. There are significant gaps in our understanding of this unusual …

Superconductivity of Metals and Cuprates covers the basic physics of superconductivity,
both the theoretical and experimental aspects. The book concentrates on important facts and …

In this article we review essential natures of superconductivity in strongly correlated electron
systems (SCES) from a universal point of view. First we summarize experimental results on …

We present here the microwave surface impedance of a high-purity crystal of YBa 2 Cu 3 O
6.99 measured at five frequencies between 1 and 75 GHz. This data set reveals the main …
