Abstract

We have studied magnetic inhomogeneity by means of spin-wave Brillouin scattering in ultrathin Co films. The distribution of perpendicular anisotropy causes a field-dependent broadening of the spin-wave spectrum. The anisotropy distribution shows a minimum for 1 monolayer (ML) of Au-interlayer at Co/Cu(1 1 1). The Co-thickness dependence of the spectrum width shows a significant increase in the magnetic inhomogeneity below 2.5 ML of Co.
