Ferromagnetic inter-layer coupling in FeSeS superconductors revealed by inelastic neutron scattering
Mingwei Ma, Philippe Bourges, Yvan Sidis +8
FeSeS superconductors are commonly considered layered van der Waals materials with negligible inter-layer coupling. Here, using inelastic neutron scattering to study…
Preferred Spin Excitations in the Bilayer Iron-Based Superconductor CaK(FeNi)As with Spin-Vortex Crystal Order
Chang Liu, Philippe Bourges, Yvan Sidis +10
The spin-orbit coupling (SOC) is a key to understand the magnetically driven superconductivity in iron-based superconductors, where both local and itinerant electrons are present a…
Hidden Magnetic Texture in the Pseudogap Phase of High-Tc
Dalila Bounoua, Yvan Sidis, Toshinao Loew +6
Despite decades of intense researches, the enigmatic pseudo-gap (PG) phase of superconducting cuprates remains an unsolved mystery. In the last 15 years, various symmetry breakings…
Polarized neutron scattering studies of magnetic excitations in iron-selenide superconductor (LiFe)ODFeSe ( = 41 K)
