Impact of spin-orbit coupling in the metallic ferromagnet SrRuO3
Recent INS experiment on SrRuO3 document a clear impact of spin-orbit coupling and Weyl points on the temperature dependent magnon dispersion. Both the anisotropy magnon gap and the magnon stiffness soften upon cooling, which can be attributed to the same Weyl physics that describes the anomalous Hall effect. SrRuO3 therefore is a prime candidate to study also other impacts of strong spin-orbit coupling. Here we propose to analyse the magnon chirality as function of temperature and q following a recent theoretical prediction of pronounced changes compared to the classical right-handedness.
