Abstract
Owing to its quasiperiodicity, magnetic quasicrystals may possibly show unique spin dynamics differing from ordinary periodic crystalline magnets. In this article we will review our recent neutron inelastic scattering study on the f-Zn-Mg-RE (RE : rare-earth) magnetic quasicrystals. A particular focus is placed on a strongly localized inelastic mode in the RE=Tb system.
