Bader Argonne National Laboratory, 9700 South Cass Avenue, Argonne, Illinois 60439 We present a theory to analyze pertubed angular correlation spectra in the framework of dynamical processes. It can be applied to study superparamagnetic properties of magnetic nanostructures, and was used recently to identify dynamical fluctuations in spin-density-wave ordered Cr. We showed that the spin fluctuations give rise to the biquadratic coupling in Fe/Cr(100) multilayers [J. Meersschaut, C. L'abbé, M. Rots, and S. D. Bader, Phys. Rev.
