New findings in resonant x-ray scattering investigation of KCuF3 orbital model system

摘要

KCuF3 single crystals grown by Bridgman method were investigated by means of Resonant X-ray Scattering: we report on both magnetic and orbital Bragg forbidden reflections. A comparison with previously obtained results on samples grown by aqueous solution method evidences strong differences in spectra: some considerations on related theoretical works are reported.
