Close correlation between magnetic properties and the soft phonon mode of the structural transition in BaFeAs and SrFeAs
D. Parshall, L. Pintschovius, D. Lamago +4
Parent compounds of Fe-based superconductors undergo a structural phase transition from a tetragonal to an orthorhombic structure. We investigated the temperature dependence of the…
Incommensurate antiferromagnetic fluctuations in single-crystalline LiFeAs studied by inelastic neutron scattering
N. Qureshi, P. Steffens, D. Lamago +7
We present an inelastic neutron scattering study on single-crystalline LiFeAs devoted to the characterization of the incommensurate antiferromagnetic fluctuations at $\mathbf{Q}=(0…
Evidence for a charge collective mode associated with superconductivity in copper oxides from neutron and x-ray scattering measurements of LaSrCuO
S. R. Park, T. Fukuda, A. Hamann +5
In superconducting copper oxides some Cu-O bond-stretching phonons around 70meV show anomalous giant softening and broadening of electronic origin and electronic dispersions have l…
Spin gap evolution upon Ca doping in the spin ladder series by inelastic neutron scattering
Guochu Deng, N. Tsyrulin, P. Bourges +6
The spin gap evolution upon Ca doping in Sr14-xCaxCu24O41 was systematically investigated using inelastic neutron scattering. We discover that the singlet-triplet spin gap excitati…
Incommensurate magnetic excitations in superconducting LiFeAs
N. Qureshi, P. Steffens, Y. Drees +8
Magnetic correlations in superconducting LiFeAs were studied by elastic and by inelastic neutron scattering experiments. There is no indication for static magnetic ordering but ine…
Inelastic neutron and x-ray scattering as probes of the sign structure of the Fe-pnictide superconducting gap
T. A. Maier, S. Graser, P. J. Hirschfeld +1
Neutron spin-flip scattering observations of a resonance in the superconducting state is often taken as evidence of an unconventional superconducting state in which the gap changes…
