Intermetallic compounds containing f-electron elements display a wealth of superconducting
phases, which are prime candidates for unconventional pairing with complex order …

In this review, we present a summary of experimental studies of magnetism in Fe-based
superconductors. The doping dependent phase diagram shows strong similarities to the …

In this review, we summarize the present status of theories of the spin fluctuation (SF)
mechanism in explaining anomalous or non-Fermi liquid behaviours and unconventional …

The basic magnetic and electronic properties of most binary compounds have been well
known for decades. The recent discovery of superconductivity at 39 K in the simple binary …

The electronic structure of heavy-fermion compounds arises from the interaction of nearly
localized 4 f-or 5 f-shell electrons (with atomic magnetic moments) with the free-electron-like …

Inelastic neutron scattering measurements on single crystals of superconducting BaFe 1.84
Co 0.16 As 2 reveal a magnetic excitation located at wave vectors (1/2 1/2 L) in tetragonal …

Neutron scattering is used to probe magnetic excitations in FeSe 0.4 Te 0.6 (T c= 14 K). Low
energy spin fluctuations are found with a characteristic wave vector (1 2 1 2 L) that …

We use inelastic neutron scattering to study magnetic excitations of the FeAs-based
superconductor BaFe 1.9 Ni 0.1 As 2 above and below its T c (<? format?>=<? format?> 20 …

Over the past two decades, unconventional superconductivity with gap symmetry other than
s wave has been found in several classes of materials, including heavy fermion, high T c …

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 …
