  journal={Nature Physics},
A comprehensive survey of the cuprate, heavy-fermion and iron-based superconductors shows a universal linear relationship between their magnetic resonance energy and superconducting gap. This result suggests that antiferromagnetic fluctuations might have a similar role in the unconventional superconductivity of these seemingly different classes of materials. Superconductivity involves the formation of electron pairs (Cooper pairs) and their condensation into a macroscopic quantum state. In… 

Momentum and Doping Dependence of Spin Excitations in Electron-Doped Cuprate Superconductors

Superconductivity in copper oxides emerges on doping holes or electrons into their Mott-insulating parent compounds. The spin excitations are thought to be the mediating glue for the pairing in

Theoretical approach to direct resonant inelastic x-ray scattering on magnets and superconductors

The capability to probe the dispersion of elementary spin, charge, orbital, and lattice excitations has positioned resonant inelastic x-ray scattering (RIXS) at the forefront of photon science. In

The superconducting feedback resonance in inelastic neutron scattering (INS) has now been found in numerous unconventional superconductors of the cuprate, ferropnictide, and heavy fermion classes.

Competing magnetic orders in the superconducting state of heavy-fermion CeRhIn5

It is shown that 5% magnetic substitution at the Ce site in CeRhIn5, either by Nd or Gd, induces a zero-field magnetic instability inside the superconducting state, suggesting that a spin-density-wave phase is stabilized in zero field by N d and Gd impurities, similarly to the case of Ce0.95Nd0.05CoIn5.

Kinetic-energy driven superconductivity in cuprate superconductors

Superconductivity in cuprate superconductors occurs upon charge-carrier doping Mott insulators, where a central question is what mechanism causes the loss of electrical resistance below the

Two Ising-like magnetic excitations in a single-layer cuprate superconductor

There exists increasing evidence that the phase diagram of the high-transition temperature (Tc) cuprate superconductors is controlled by a quantum critical point. According to one distinct

High-energy magnetic excitations from heavy quasiparticles in CeCu2Si2

Magnetic fluctuations is the leading candidate for pairing in cuprate, iron-based, and heavy fermion superconductors. This view is challenged by the recent discovery of nodeless superconductivity in

Theory of nodal s±-wave pairing symmetry in the Pu-based 115 superconductor family

This calculation demonstrates that the s+− wave pairing strength is stronger than the previously thought d-wave pairing; and more importantly, this pairing state allows for the existence of nodal quasiparticle states in iron-based superconductors.

Non-BCS Superconductivity in Cuprates from Attraction of Spin Vortices

We propose a non-BCS mechanism for superconductivity (SC) in hole-underdoped cuprates based on a gauge approach to the t-J model. The gluing force is a long-range attraction between spin vortices



Superconductivity mediated by spin fluctuations in the heavy-fermion compound UPd2 Al3

It is well known that any weak attractive electron–electron interaction in metals can in principle cause the formation of Cooper pairs, which then condense into a superconducting ground state. In

A new family of superconductors containing layers of iron arsenide has attracted considerable interest because of their high transition temperatures (T{sub c}), some of which are >50 K, and because

Interplay of electron–lattice interactions and superconductivity in Bi2Sr2CaCu2O8+δ

Formation of electron pairs is essential to superconductivity. For conventional superconductors, tunnelling spectroscopy has established that pairing is mediated by bosonic modes (phonons); a peak in

Neutron scattering from magnetic excitations in Bi2Sr2CaCu2O8+δ

Many of the physical properties of the copper oxide high-temperature superconductors appear to defy the conventional ‘one-electron’ theory of metals. The development of alternative theories

Neutron-spin resonance in the optimally electron-doped superconductor Nd1.85Ce0.15CuO4-delta.

Inelastic neutron scattering is used to probe magnetic excitations of an optimally electron-doped superconductor Nd1.85Ce0.15CuO4-delta above and below its superconducting transition temperature Tc=25 K to form a resonance that must be fundamental to the mechanism of high-Tc superconductivity.

Abrupt onset of a second energy gap at the superconducting transition of underdoped Bi2212

Underdoped high-Tc superconducting copper oxides is found to have a gap that opens at Tc and has a canonical (BCS-like) temperature dependence accompanied by the appearance of the so-called Bogoliubov quasi-particles, a classical signature of superconductivity.

The first spatially resolved measurements of gap formation in a high-Tc superconductor are reported, measuring on Bi2Sr2CaCu2O8+δ samples with different Tc values using scanning tunnelling microscopy and finding that every pairing gap develops locally at a temperature Tp, following the relation 2Δ/kBTp = 7.5.

Nearly isotropic superconductivity in (Ba,K)Fe2As2

Measurements of the electrical resistivity in single crystals of (Ba,K)Fe2As2 in a magnetic field up to 60 T find that the superconducting properties are in fact quite isotropic, being rather independent of the direction of the applied magnetic fields at low temperature.
