      abstract     = {Motivated by recent studies on current-driven domain-wall
                      motion we have explored the dispersion of spin waves
                      (magnons) in ultrathin nickel/cobalt multilayers. The layers
                      are grown epitaxially on Cu(100) surfaces and consist of n
                      nickel single-atom layers, each topped by a cobalt bilayer
                      with n=2, 3, and 4(n×Ni1Co2). Layers of the type 2×Ni2Co1
                      are also studied. While parallel to the film plane the
                      magnon dispersion is nearly equal to that of pure cobalt
                      films, magnons with wave vectors perpendicular to the film
                      plane (standing waves) are considerably softened. The
                      softening is attributed to a reduction of the effective
                      interlayer exchange coupling between the two layers next to
                      the interface with the Cu(100) substrate.},
