      abstract     = {The magnon dispersion of ferromagnetic SrRuO3 was studied
                      by inelastic neutron scattering experiments on single
                      crystals as a function of temperature. Even at low
                      temperature the magnon modes exhibit substantial broadening
                      pointing to strong interaction with charge carriers. We find
                      an anomalous temperature dependence of both the magnon gap
                      and the magnon stiffness, which soften upon cooling in the
                      ferromagnetic phase. Both effects trace the temperature
                      dependence of the anomalous Hall effect and can be
                      attributed to the impact of Weyl points, which results in
                      the same relative renormalization in the spin stiffness and
                      magnon gap.},
