Suppression of low-energy longitudinal spin-excitations in Co-underdoped BaFe2As2
F. Waßer, C. H. Lee, K. Kihou +4
Polarized inelastic neutron scattering experiments were performed to study magnetic excitations in the normal and superconducting phases of Co-underdoped BaFeAs, which exhi…
Suppression of spin-exciton state in hole overdoped iron-based superconductors
C. H. Lee, K. Kihou, J. T. Park +7
The mechanism of Cooper pair formation in iron-based superconductors remains a controversial topic. The main question is whether spin or orbital fluctuations are responsible for th…
Anisotropy of incommensurate magnetic excitations in slightly overdoped BaKFeAs probed by polarized inelastic neutron scattering experiments
N. Qureshi, C. H. Lee, K. Kihou +3
Polarized neutron scattering experiments on the slightly overdoped superconductor BaKFeAs reveal broad magnetic resonance scattering peaking at approximatel…
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…
Universality of dispersive spin-resonance mode in superconducting BaFe2As2
C. H. Lee, P. Steffens, N. Qureshi +5
Spin fluctuations in superconducting BaFe2(As1-xPx)2 (x=0.34, Tc = 29.5 K) are studied using inelastic neutron scattering. Well-defined commensurate magnetic signals are observed a…
Splitting of resonance excitations in nearly optimally doped Ba(Fe0.94Co0.06)2As2: an inelastic neutron scattering study with polarization analysis
Paul Steffens, C. H. Lee, N. Qureshi +4
Magnetic excitations in Ba(Fe0.94Co0.06)2As2 are studied by polarized inelastic neutron scattering (INS) above and below the superconducting transition. In the superconducting stat…
