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…
Electron-phonon coupling in the conventional superconductor YNiBC at high phonon energies studied by time-of-flight neutron spectroscopy
F. Weber, S. Rosenkranz, L. Pintschovius +9
We report an inelastic neutron scattering investigation of phonons with energies up to 159 meV in the conventional superconductor YNiBC. Using the SWEEP mode, a newly devel…
Competition between commensurate and incommensurate magnetic ordering in Fe(1+y)Te
D. Parshall, G. Chen, L. Pintschovius +4
The Fe1+y Te1-x Sex compounds belong to the family of iron-based high temperature superconductors, in which superconductivity often appears upon doping antiferromagnetic parent com…
Effects of charge inhomogeneities on elementary excitations in La_{2-x}Sr_xCuO_4
S. R. Park, A. Hamann, L. Pintschovius +7
Purely local experimental probes of many copper oxide superconductors show that their electronic states are inhomogeneous in real space. For example, scanning tunneling spectroscop…
Direct observation of the superconducting gap in phonon spectra
F. Weber, A. Kreyssig, L. Pintschovius +5
We show that the superconducting energy gap can be directly observed in phonon spectra, as predicted by recent theories. In addition, since each phonon probes the gap on only a…
