Inelastic neutron scattering has been used to measure the low-energy spin excitations in the ordered charge-stripe phase of La{sub 2}NiO{sub 4+{delta}} with {delta}=0.133 . Spin-wave-like excitations disperse away from the incommensurate magnetic superlattice points with a velocity {approximately}60{percent} of that in the {delta}=0 compound. Incommensurate inelastic peaks remain well resolved up to at least twice the magnetic ordering temperature. Paramagnetic scattering from a {delta}=0.105…

The study indicates the prerequisite to consider a discommensurated spin stripe unit with proper out-of-plane and in-plane exchange interactions in between Ni^{2+} spins to describe the observed spin wave characteristics in Pr_{3/2}Sr_{1/2]NiO_{4}.

Direct observation of dynamic charge stripes in La2-xSrxNiO4.
The detection of critical lattice fluctuations, driven by charge-stripe correlations, in La2-xSrxNiO4 using inelastic neutron scattering is reported, which opens the way towards the quantitative theory of dynamic stripes and for directly detecting dynamical charge stripes in other strongly correlated systems, including high-temperature superconductors such as La 2-x SrxCuO4.
