Spin-excitation anisotropy in the bilayer iron-based superconductor CaKFe_{4}As_{4}
We use polarized inelastic neutron scattering to study the spin-excitation anisotropy in the bilayer iron-based superconductor CaKFe_{4}As_{4} (T_{c}=35 K). In the superconducting state, both odd and even L modulations of spin resonance have been observed in our previous unpolarized neutron-scatteri...
