Inter- and intratrimer excitations in the multiferroic Ba3NbFe3Si2O14
Abstract
Elastic and inelastic neutron-scattering experiments have been performed on single crystals of the multiferroic Ba3NbFe3Si2O14. It is found that the organization of the spin clusters into true long-range ordered states occurs by the following process: (i) by 60 K, there is evidence for short-range ordered triangular Fe clusters of spins, (ii) below 40 K, the clusters begin to form long-range ordered structures as a spin-wave spectrum develops, …
