      abstract     = {We report on an x-ray resonance exchange scattering (XRES)
                      study of multiferroic TbMnO3. Magnetic scattering is
                      observed close to the Mn K edge and the Tb L-III and L-II
                      edges. Surprisingly, Tb shows XRES also in the paraelectric
                      phase, where neutron diffraction results suggested the 4f
                      moments to be disordered. The temperature dependence of the
                      XRES intensities shows a distinct kink close to the
                      ferroelectric transition temperature T-C for all absorption
                      edges. We were able to model the temperature dependence for
                      all edges, assuming a strong coupling of Mn and Tb magnetism
                      via the spin polarized 5d conduction band. We argue that the
                      hybridization between Mn and Tb states is a prerequisite for
                      the multiferroic effect in this material.},
