Standing Spin Waves in an Antiferromagnetic Molecular Cr6 Horseshoe
arXiv:0706.0247 · doi:10.1209/0295-5075/79/17003
Abstract
The antiferromagnetic molecular finite chain Cr6 was studied by inelastic neutron scattering. The observed magnetic excitations at 2.6 and 4.3 meV correspond, due to the open boundaries of a finite chain, to standing spin waves. The determined energy spectrum revealed an essentially classical spin structure. Hence, various spin-wave theories were investigated in order to assess their potential for describing the elementary excitations of finite spin systems.
