      abstract     = {We demonstrate that ferromagnetic and antiferromagnetic
                      excitations can be triggered by the dynamical spin
                      accumulations induced by the bulk and surface contributions
                      of the spin Hall effect. Due to the spin-orbit interaction,
                      a time-dependent spin density is generated by an oscillatory
                      electric field applied parallel to the atomic planes of
                      Fe/W(110) multilayers. For symmetric trilayers of Fe/W/Fe in
                      which the Fe layers are ferromagnetically coupled, we
                      demonstrate that only the collective out-of-phase precession
                      mode is excited, while the uniform (in-phase) mode remains
                      silent. When they are antiferromagnetically coupled, the
                      oscillatory electric field sets the Fe magnetizations into
                      elliptical precession motions with opposite angular
                      velocities. The manipulation of different collective
                      spin-wave dynamical modes through the engineering of the
                      multilayers and their thicknesses may be used to develop
                      ultrafast spintronics devices. Our work provides a general
                      framework that probes the realistic responses of materials
                      in the time or frequency domain.},
