Abstract
The orbital distribution of the spin fluctuation in the iron-based superconductors (IBSs) is the key information needed to understand the magnetism, superconductivity and electronic nematicity in these multi-orbital systems. In this work, we propose that the resonant inelastic X-ray scattering (RIXS) technique can be used to probe selectively the spin fluctuation on different Fe 3d orbitals. In particular, the spin fluctuation on the three t2g orbitals, namely, the 3dxz, 3dyz and the 3dxy orbital, can be selectively probed in the scattering geometry by aligning the direction of the outgoing photon in the y-, x- and z-direction. Such orbital-resolved information on the spin fluctuation is invaluable for the study of the orbital-selective physics in the IBSs and can greatly advance our understanding of the relation between orbital ordering and spin nematicity in the IBSs and the orbital-selective pairing mechanism in these multi-orbital systems.
