yThe x-ray resonant scattering cross-section of K2ReCl6 has been studied for energies near the L edges of rhenium. Below the Neel temperature of T-N similar to 11 K, additional peaks appear when the photon energy is tuned to the L-II or L-III edges. The peaks are found to rotate the incident (linear) polarization, and have a Lorentzian lineshape in energy. The peaks are ascribed to resonant magnetic scattering, where a dipolar transition connects 2p-5d states. At resonance the scattering amplitude is of order similar tor(0) per atom, roughly two orders of magnitude greater than that of the bare magnetic scattering.
