The ferromagnetic superconductor URhGe has been investigated by high field magnetic circular dichroism (XMCD) at the U M4,5, Rh L2,3, and Ge K edges at 2.1 K and at applied fields up to 17 T. The XMCD performed at the M4,5 absorption edges allows us to determine the spectroscopic branching ratio and the 5f electron contribution to the valence spin-orbit interaction. Combination with polarized neutron diffraction results allows us to derive the individual U orbital and spin moments and the magnetic-dipole contribution ⟨Tz⟩. The results are discussed against predictions of the electronic band structure calculations by the density functional theory plus Coulomb U, including spin-orbit coupling.
