Abstract

Ferromagnetic SrRuO3 was proposed as a candidate material to exhibit an inverted magnon chirality due to a strong impact of spin-orbit coupling and Weyl fermions. By polarized inelastic neutron scattering under magnetic fields we determine the chirality of the ferromagnetic zone-center excitation as a function of temperature. Well in the ferromagnetic phase the excitation is perfectly chiral with the usual (right-handed) sign and only when the spontaneous magnetization is almost completely suppressed the chirality of the zone center magnetic excitations is reduced but does not change sign.
