摘要：

We measure quantized spin waves excited by a spatially inhomogeneous pulsed magnetic field in patterned NiFe thin films by inductive detection of the dynamic magnetization. When anisotropy and numerically calculated demagnetizing fields are included in the magnetostatic Damon-Eshbach spin-wave dispersion relation, the predicted mode frequencies agree closely with measurements. Micromagnetic calculations predict the correct mode frequencies and agree remarkably well with time-domain measurements.
