Abstract
We present inelastic neutron scattering measurements of magnetic excitations in stripe ordered Pr3/2Sr1/2NiO4 at T similar to 10 K. For the observed magnetic incommensurability epsilon = 0.4, we have incorporated a stripe discommensuration model in our linear spin wave calculation and obtained best agreement with the measured spin wave dispersion, especially to explain the symmetrical outward shift of the magnetic peaks from Neel ordered zone center in energy range 35 to 45 meV. Our study indicates the prerequisite to consider a discommensurated spin stripe unit with proper out-of-plane and in-plane exchange interactions in between Ni2+ spins to describe the observed spin wave characteristics in Pr3/2Sr1/2NiO4.
