چکیده
Magnetic excitations in the itinerant magnet SrRuO${}_{3}$ were studied by combination of various neutron scattering techniques. Although a Heisenberg local-moment model well describes low-energy magnon dispersion, severe suppression intensities and stiffening dispersion at high energies, as strong broadening, are clear finger prints character magnetism SrRuO${}_{3}$.

Tunable Magnon Weyl Points in Ferromagnetic Pyrochlores.
The dispersion relations of magnons in ferromagnetic pyrochlores with Dzyaloshinskii-Moriya interaction are shown to possess Weyl points, i. e., pairs of topologically nontrivial crossings of two magnon branches with opposite topological charge. As a consequence of their topological nature, their projections onto a surface are connected by magnon arcs, thereby resembling closely Fermi arcs of e...
متن کاملCoherent magnon optics in a ferromagnetic spinor Bose-Einstein condensate.
We measure the dispersion relation, gap, and magnetic moment of a magnon in the ferromagnetic F = 1 spinor Bose-Einstein condensate of (87)Rb. From the dispersion relation we measure an average effective mass 1.033(2)(stat)(10)(sys) times the atomic mass, as determined by interfering standing and running coherent magnon waves within the dense and trapped condensed gas. The measured mass is high...
متن کاملS-duality and the giant magnon dispersion relation
We use S-duality and planarity to propose an argument for the non-renormalization of the dispersion relation of giant magnon solutions in type IIB string theory on Ad S5 × S5. We compute the spectrum of giant magnons for (p, q)-strings from field theory at strong coupling by using the central charge properties of electrically and magnetically charged supersymmetric states in the Coulomb branch ...
متن کاملMagnon softening and damping in the ferromagnetic manganites due to orbital correlations
We present a theory for spin excitations in ferromagnetic metallic manganites and demonstrate that orbital fluctuations have strong effects on the magnon dynamics in the case these compounds are close to a transition to an orbital ordered state. In particular we show that the scattering of the spin excitations by low-lying orbital modes with cubic symmetry causes both the magnon softening and d...
متن کاملMagnon damping by magnon-phonon coupling in manganese perovskites
Inelastic neutron scattering was used to systematically investigate the spin-wave excitations ~magnons! in ferromagnetic manganese perovskites. In spite of the large differences in the Curie temperatures (TC’s! of different manganites, their low-temperature spin waves have very similar dispersions with the zone-boundary magnon softening and broadening that cannot be explained by the canonical d...
