Abstract
We report an inelastic neutron scattering study on the magnetic excitations of Pr2NiO4+delta (delta similar to 0.24 +/- 0.01) at T = 10 K. Spin stripe ordering becomes pronounced below similar to 220 K with an incommensurability epsilon approximate to 0.346, and a strong influence of interstitial oxygen is identified on establishing a long-range spin stripe ordering. Apart from the Goldstone modes emerging from the magnetic satellites (q(m)), multiple homologous modes are observed along the spin stripe modulation separated by Delta q(m) approximate to 0.076 in reciprocal lattice units, which is interpreted by the internal periodicity of the long-range ordered discommensurated spin stripes.
