Inelastic neutron scattering study of icosahedral AlFeCu quasicrystal
Résumé
Dynamical properties of quasiperiodic structures are rather tricky and far from being understood. For quasicrystals only little information is available both theoretically and experimentally. In this paper we present new experimental results obtained by inelastic neutron scattering on a monodomain quasicrystal of Al63Cu25Fe12 already investigated in a previous study [1]. In section 1 we recall the basic features of the quasiperiodic structures and briefly review theoretical works on the dynamics of quasicrystals which can be of some help to appreciate the experimental data presented in section 2 and discussed in section 3.
