Coherence–incoherence crossover in the normal state of iron oxypnictides and importance of Hund's rule coupling (2008, background): “In the parent compound, the resistivity exhibits a peak at 150 K [1] followed by a sharp drop, which is due to a structural transition from tetragonal (space group P4/nmm) to orthorhombic structure (space group Cmma) [3, 7] followed by a spin density wave transition [5, 6] at lower temperatures.”
First principles design of spintronics materials (2016, background): “5d) are the key ingredient for Fe-based superconductors [83], in which Fe atoms are tetrahedrally coordinated by As or Se atoms and take a formal +2 state, bearing a high spin of S = 2.”
Magnetism and charge dynamics in iron pnictides (2010, methodology): “To extract the anisotropy of the electronic structure, we integrate the partial density of states of xz and yz orbitals (Axz(ω) and Ayz(ω)) to obtain their occupations, and evaluate their difference 1n(3)= ∫ 0 −3 [Axz(ω)−Ayz(ω)]dω/(1/2) ∫ 0 −3 [Axz(ω)+ Ayz(ω)]dω).”

Magnetic order close to superconductivity in the iron-based layered LaO1-xFxFeAs systems (2008, background): “The BT-1 diffractometer has a Ge(3, 1, 1) monochromator and an incident beam wavelength of l 5 2.”
Very High Field Two-Band Superconductivity in LaFeAsO_0.89F_0.11 (2008, background): “1 with the transition temperature of Tc = 26K [1-4] has been quickly followed by reports of even higher Tc = 41K in CeFeAsO0.”
In-plane electronic anisotropy of underdoped ‘122’ Fe-arsenide superconductors revealed by measurements of detwinned single crystals (2011, background): “…and early seminal papers describe the occurrence of superconductivity in materials which have commonly become known as ‘1111’ (for example LaFeAsO (Kamihara et al 2008)), ‘122’ (for example BaFe2As2 (Rotter et al 2008a, 2008b)), ‘111’ (LiFeAs (Tapp et al 2008) and NaFeAs (Parker et al 2009))…”
Tellurium substitution effect on superconductivity of the α-phase iron selenide (2008, background): “The tetragonal phase α-FeSe with PbO-type structure has the same planar sublattice as the layered Fe based quaternary oxypnictides, which is the first system where Fe-element plays the key role to the occurrence of superconductivity [4].”
Spin waves and magnetic exchange interactions in CaFe 2 As 2 (2009, background): “1a), one can see three clear plumes of scattering arising from the in-plane antiferromagnetic zone centres Q= (1,−2), (1, 0) and (1, 2) r.”
Satellites and large doping and temperature dependence of electronic properties in hole-doped BaFe2As2 (2011, methodology): “In the constrained RPA (cRPA) method [1, 2] we first define a one-particle subspace {ψd} of the low-energy space, which we call the “d subspace”, and label the rest of the Hilbert space by {ψr} (“r subspace”).”
