The magnetic excitations in ferromagnetic SrRuO$_3$ were studied by inelastic neutron scattering combining experiments on triple-axis and time-of-flight spectrometers with and without polarization analysis. A quadratic spin-wave dispersion with an an

Combining quasistatic and time-resolved transport measurements with x-ray and neutron diffraction experiments we study the nonequilibrium states that arise in pure and in Ti-substituted ${\mathrm{Ca}}_{2}{\mathrm{RuO}}_{4}$ under the application of c

The magnetization-density distribution in the metallic ferromagnet SrRuO$_3$ was studied by means of polarized neutron diffraction. The analyzes by multipole refinements and by the maximum entropy method consistently reveal a strong polarization of a

The magnon dispersion of ferromagnetic SrRuO_{3} 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 inter

The magnetic shape-memory effect -- magnetic-field-induced plastic deformations that return to the initial shape upon heating -- is intensively studied in intermetallic Heusler materials. Here, the authors see this effect for the metallic oxide SrRuO

The magnon dispersion of ${\mathrm{Ca}}_{2}{\mathrm{RuO}}_{4}$ has been studied by polarized and unpolarized neutron scattering experiments on crystals containing 0, 1, and 10% of Ti. Ti is inserted in order to enable the growth of large, partially d

Inelastic neutron scattering experiments on Sr_{2}RuO_{4} determine the spectral weight of the nesting induced magnetic fluctuations across the superconducting transition. There is no observable change at the superconducting transition down to an ene
