Neutron inelastic scattering experiments were carried out on a mixed valent (V 4Ο© /V 5Ο© ) vanadate LiV 2 O 5 . Observed spin wave excitations suggest that the antiferromagnetic (AF) periodicity along the b-axis (chain) direction is characterized by the doubling of the chemical unit cell. A strong di

β¦ Synopsis
We summarize our recent inelastic neutron scattering results on NaV 2 O 5 . They provided the first experimental evidences for deviations from a simple One-dimensional (1D) spin-Peierls scenario in explaining the formation of the low-temperature singlet ground state in this compound. These neutron scattering results are discussed in the context with recent theoretical and experimental findings pointing towards a "zig-zag" type charge ordering realized in the low-temperature phase.

We have performed time-of-flight neutron scattering measurements on a single crystal of the intermediate valence compound CePd 3 . At 10 K, a Kondo-esque inelastic magnetic scattering peak occurs near DE ΒΌ 60 meV with maximum intensity for momentum transfer Q near the Γ° 1 2 ; 1 2 ; 0Γ zone boundary.
