A nonperturbative approach giving the spin-energy coupling effects present in the magnetization fluctuation spectra is developed for the quantum one-dimensional ferromagnetic chain to explain the features observed in CsNiF3 by new experiments employing polarized neutrons.

Abstract
A nonperturbative approach giving the spin-energy coupling effects present in the magnetization fluctuation spectra is developed for the quantum one-dimensional ferromagnetic chain to explain the features observed in CsNiF3 by new experiments employing polarized neutrons. Quantum effects are found to be essential to reproduce the features observed in the data.File in questo prodotto:
