Strong Spin Resonance Mode associated with suppression of soft magnetic ordering in Hole-doped Ba1-xNaxFe2As2
F. Wasser, J. -T. Park, S. Aswartham +6
Spin-resonance modes (SRM) are taken as evidence for magnetically driven pairing in Fe-based superconductors, but their character remains poorly understood. The broadness, the spli…
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…
Spin reorientation in Na-doped BaFeAs studied by neutron diffraction
F. Wasser, A. Schneidewind, Y. Sidis +4
We have studied the magnetic ordering in Na doped BaFeAs by unpolarized and polarized neutron diffraction using single crystals. Unlike previously studied FeAs-based compou…
