Electronic structure of the iron-based superconductor LaOFeP
D. H. Lu, M. Yi, S. -K. Mo +8
The recent discovery of superconductivity in the so-called iron-oxypnictide family of compounds has generated intense interest. The layered crystal structure with transition metal…
Quantum oscillations in the parent magnetic phase of an iron arsenide high temperature superconductor
Suchitra E. Sebastian, J. Gillett, N. Harrison +3
We report quantum oscillation measurements in SrFe2As2 - which is an antiferromagnetic parent of the iron-arsenide family of superconductors - known to become superconducting under…
Unconventional sign-reversing superconductivity in LaFeAsO_(1-x)F_x
I. I. Mazin, D. J. Singh, M. D. Johannes +1
We argue that the newly discovered superconductivity in a nearly magnetic, Fe-based layered compound is unconventional and mediated by antiferromagnetic spin fluctuations, though d…
Fermi surface and van Hove singularities in the itinerant metamagnet Sr3Ru2O7
A. Tamai, M. P. Allan, J. F. Mercure +8
The low-energy electronic structure of the itinerant metamagnet Sr3Ru2O7 is investigated by angle resolved photoemission and density functional calculations. We find well-defined q…
LaFeAsOF: A low carrier density superconductor near itinerant magnetism
D. J. Singh, M. H. Du
Density functional studies of 26K superconducting LaFeAs(O,F) are reported. We find a low carrier density, high density of states, and modest phonon frequencies relative t…
