Title

Anomalous spin dynamics in Ca-doped SrRuO3

Abstract

Ferromagnetic SrRuO3 exhibits an anomalous temperature dependence of the magnon gap and of the stiffness that could be attributed to the impact of Weyl points in the electronic structure. Here we propose to apply a similar analysis to two compounds with partial substitution of Sr by Ca. The Ca content reduces the ferromagnetic transition temperature as well as the ordered moment, while the size of the local magnetic anisotropy seems to little change. As Weyl points were already established also for these substituted materials we can deepen the analysis of the interplay of Weyl points and the topology of the electronic structure with the spin dynamics.
