Abstract
In Fe/Pd and Fe/W multilayers the complete, theoretically predicted band of collective magnetostatic spin-wave excitations has been observed. Despite the large number of bilayers (49–90) discrete spin-wave modes have been found in the upper half of the band. For Fe/Pd multilayers the saturation magnetization shows a monotonic reduction of up to 30% with decreasing modulation wavelength (down to 33 Å), which is not found in the Fe/W multilayer.Keywords
