      abstract     = {Topological noncollinear magnetic phases of matter are at
                      the heart of many proposals for future information
                      nanotechnology, with novel device concepts based on
                      ultrathin films and nanowires. Their operation requires
                      understanding and control of the underlying dynamics,
                      including excitations such as spin waves. So far, no
                      experimental technique has attempted to probe large
                      wave-vector spin waves in noncollinear low-dimensional
                      systems. In this paper, we explain how inelastic electron
                      scattering, being suitable for investigations of surfaces
                      and thin films, can detect the collective spin-excitation
                      spectra of noncollinear magnets. To reveal the
                      particularities of spin waves in such noncollinear samples,
                      we propose the usage of spin-polarized electron-energy-loss
                      spectroscopy augmented with a spin analyzer. With the spin
                      analyzer detecting the polarization of the scattered
                      electrons, four spin-dependent scattering channels are
                      defined, which allow us to filter and select specific
                      spin-wave modes. We take as examples a topological
                      nontrivial skyrmion lattice, a spin-spiral phase, and the
                      conventional ferromagnet. Then we demonstrate that,
                      counterintuitively and in contrast to the ferromagnetic
                      case, even non-spin-flip processes can generate spin waves
                      in noncollinear substrates. The measured dispersion and
                      lifetime of the excitation modes permit us to fingerprint
                      the magnetic nature of the substrate.},
