Impurity-induced states in conventional and unconventional superconductors
TL;DR: In this article, the authors provide a unified framework for describing quasi-localized states in the vicinity of impurity sites in conventional and unconventional superconductors and show that these fluctuations affect the density of states and are, strictly speaking, gapless in the presence of an arbitrarily small concentration of magnetic impurities.

Coexistence of superconductivity and ferromagnetism in URhGe
Dai Aoki,Andrew Huxley,Eric Ressouche,Daniel Braithwaite,Jacques Flouquet,Jean-Pascal Brison,Elsa Lhotel,C. Paulsen +7 more
TL;DR: It is shown that the ferromagnet URhGe is superconducting at ambient pressure, and the thermodynamic signature of the transition is found—its form is consistent with asuperconducting pairing of a spin-triplet type, although further testing with cleaner samples is needed to confirm this.

Defects in correlated metals and superconductors
TL;DR: In this paper, the effect of impurities on local charge and spin degrees of freedom in 1D antiferromagnetically correlated systems was investigated. But the results were limited to the Tc cuprate normal state, which is not soluble in 2 or 3 dimensions and so few exact results are known.

Heavy-electron metals: new highly correlated States of matter.
Zachary Fisk,D. W. Hess,C. J. Pethick,David Pines,James L. Smith,Joe D. Thompson,J. O. Willis +6 more
TL;DR: The physical origin of the large mass and unusual superconducting and magnetic properties is the strong coupling between the conduction electrons and the local f-electron moment fluctuations characteristic of these materials.

Theory of Heavy Fermion Systems
TL;DR: In this paper, the authors presented a study on theory of heavy fermion systems and showed that some of the features of the single Kondo impurity problem appear in an enhanced form simply, because there is at least one magnetic ion per unit cell.

Heavy-fermion systems
TL;DR: In this paper, a review of the state-of-the-art results for heavy-fermion superconductivity is presented, and several correlations between properties are pointed out, including the observation that a low value of the Wilson ratio appears to correlate with the occurrence of superconductivities.

Classical Spins in Superconductors
TL;DR: In this paper, it was shown that there exists a localized excited state in the energy gap in a superconductor with a classical spin and at finite concentration localized excited states around classical spins form an "impurity band".

Possibility of Coexistence of Bulk Superconductivity and Spin Fluctuations in UPt3
TL;DR: In this article, it was shown that UPt3 is a spin-fluctuation system and if true, this is the first coexistent superconductor-spinfluctuated system.

p-Wave Superconductivity in UBe13
TL;DR: The specific heat in the superconducting state of UBe13 shows marked deviations from BCS theory and obeys a T 3 rather than an exponential law at low temperatures.
