Recently, high-transition-temperature (high-Tc) superconductivity was discovered in the iron pnictide RFeAsO(1-x)F(x) (R, rare-earth metal) family of materials. We use neutron scattering to study the structural and magnetic phase transitions in CeFeAsO(1-x)F(x) as the system is tuned from a semimetal to a high-Tc superconductor through fluorine (F) doping, x. In the undoped state, CeFeAsO develops a structural lattice distortion followed by a collinear antiferromagnetic order with decreasing… Expand

Paper Mentions

The electronic phase diagram of the LaO(1-x)F(x)FeAs superconductor.
TLDR
The results strongly question the relevance of quantum critical behaviour in iron pnictides and prove a strong coupling of the structural orthorhombic distortion and the magnetic order both disappearing at the phase boundary to the superconducting state. Expand
Coexistence of static magnetism and superconductivity in SmFeAsO(1-x)F(x) as revealed by muon spin rotation.
TLDR
A muon spin rotation study on SmFeAsO(1-x)F(x), with x=0-0.30 that shows that, as in the cuprates, static magnetism persists well into the superconducting regime, suggests that the proximity to magnetic order and associated soft magnetic fluctuations, rather than strong electronic correlations in the vicinity of a Mott-Hubbard transition, may be the key ingredients of high-Tc superconductors. Expand
Electronic and magnetic phase diagram of beta-Fe(1.01)Se with superconductivity at 36.7 K under pressure.
TLDR
The magnetic and electronic phase diagram of beta-Fe(1.01)Se is reported, which shows a marked change in volume at the same time as T(C) rises, owing to a collapse of the separation between the Fe(2)Se(2), and it is reported that at higher pressures, Fe(1)Se transforms to a hexagonal NiAs-type structure and exhibits non-magnetic behaviour. Expand
Phase separation and suppression of the structural and magnetic transitions in superconducting doped iron tellurides, Fe(1+x)Te(1-y)S(y).
TLDR
It is shown that on sulfur substitution, Fe(1+x)Te(1-y)S(y) becomes orthorhombic (Pmmn) at low temperature for 0 ≤ y ≤ 0.05, where the greatly suppressed magnetic scattering is now incommensurate at q = (0.5-δ 0 0.5). Expand
Pressure-induced phase transitions and correlation between structure and superconductivity in iron-based superconductor Ce(O(0.84)F(0.16))FeAs.
TLDR
The structure analysis shows a discontinuity in the pressure dependences of the Fe-As and Ce-(O, F) bond distances, as well as the As-Fe-As-Ce bond angles in the transition region, which correlates with the change in T(c) of this compound upon compression. Expand

Phase transition in CaFeAsH: bridging 1111 and 122 iron-based superconductors.
TLDR
The nature of the ST and MT in CaFeAsH is intermediate in character, between the second- order transition for 1111-type compounds and the first-order transition for other 11- and 122- type compounds. Expand
Magnetism in Fe-based superconductors.
TLDR
Studies of the spin dynamics of the parent compounds show that the interactions are best characterized as anisotropic three-dimensional interactions, and analysis of the low temperature spin waves under the assumption of a Heisenberg Hamiltonian indicates strong in-plane anisotropy with a significant next-nearest-neighbor interaction.
