Spin-Excitations Anisotropy in the Bilayer Iron-Based Superconductor CaKFe $_{4}$ As $_{4}$

Tao Xie, Chang Liu, Frederic Bourdarot +3

We use polarized inelastic neutron scattering to study the spin-excitations anisotropy in the bilayer iron-based superconductor CaKFe $_{4}$ As $_{4}$ ( $T_{c}$ = 35 K). In the superconducti…
