Spin dynamics in stripe-ordered La5/3Sr1/3NiO4.

Original language description

Polarized- and unpolarized-neutron inelastic scattering has been used to measure the spin excitations in the striped spin-charge-ordered phase of La5/3Sr1/3NiO4. Above 30 meV, sharp magnetic modes are observed characteristic of a static stripe lattice. This part of the energy spectrum is described well by a linear spin-wave model with intrastripe and interstripe exchange interactions between neighboring Ni spins given by J = 15 +/- 1.5 meV and J' = 7.5 +/- 1.5 meV, respectively. A pronounced suppressionand broadening of the magnetic fluctuations in a band between 10 meV and 25 meV is suggestive of coupling to collective motions of the stripe domain walls.
