The Chemical Record, 2011
AbstractThe present status of organic superconductors of charge‐transfer (CT) type based on donor molecules is reviewed. Along with the superconducting phases of such materials and also of oxide superconductors, reside spin‐ordered phases such as spin‐density wave (SDW) and antiferromagnetic (AF) phases.

Chemical Reviews, 2021
Superconductors with exotic physical properties are critical to current and future technology. In this review, we highlight several important superconducting families and focus on their crystal structure, chemical bonding, and superconductivity correlations.

Philosophical Magazine B, 2001
Abstract With a view to investigating the nature of weak links in granular superconductors at very dilute level, we have studied the low-field microwave absorption signal (below about 50 G) in the electron paramagnetic resonance mode of detection in samples of Tl2BaCa2Cu2O8+δ and YBa2Cu3O7-δ at different dilution levels in the Al2O3 matrix.

Tunneling Into Superconductors
Physical Review Letters, 1962The tunneling of electrons through a thin insulating layer between a normal and a superconducting metal is discussed. A previous derivation is examined to bring out the connection with the semiconductor model of a superconductor, and the quasi-particle excitations in normal and superconducting states are discussed.

“Fluctuoscopy” of Superconductors
2011Study of fluctuation phenomena in superconductors (SCs) is the subject of great fundamental and practical importance. Understanding of their physics allowed to clear up the fundamental properties of SC state. Being predicted in 1968, one of the fluctuation effects, namely paraconductivity, was experimentally observed almost simultaneously.

Refrigeration for superconductors
Proceedings of the IEEE, 2004Temperatures in the range of 0.05 to 80 K are required for most applications of superconductors. Refrigeration powers range from fractions of a watt for many electronic applications to kilowatts for some large magnet and power applications. This paper reviews the various types of refrigeration methods currently available to meet the needs of various ...

Journal of Superconductivity and Novel Magnetism, 2006
The vortex pinning force of superconductor(S)/normal-metal(N) multilayers, Nb/Ti and Nb100−xTix/Ti, and superconductor(S)/superconductor(S′) multilayers, Nb100−xTix/Nb and Nb28Ti72/Nb65Ti35, has been studied as a function of the layer thickness d for various compositions of x.

Abstract Superconductivity is a major research field in which the use of muons has made an important contribution. Muons measure the London penetration depth, the distance over which the superconductor screens an external magnetic field.

THEORY OF DIRTY SUPERCONDUCTORS
Journal of Physics and Chemistry of Solids, 1959Abstract A B.C.S. type of theory (see Bardeen , Cooper and Schreiffer , Phys. Rev. 108, 1175 (1957)) is sketched for very dirty superconductors, where elastic scattering from physical and chemical impurities is large compared with the energy gap.
