Abstract
An outline of a quantum approach to multi-kink profiles as coherent states in a ferromagnetic chain is given. Relying on the continuum and harmonic approximation the influence of the out-of-plane fluctuations on the stability and dynamics of multi-kink structures in a finite chain is studied and compared with the stability and dynamics of single-kink profiles in an infinite chain. Even in the harmonic approximation, very few modes are diagonal. The multi-kink structure does not exhibit a 'zero-frequency' Goldstone mode. This is a consequence of the out-of-plane fluctuations.
