Spin excitations in stripe-ordered La2-xSrxNiO4 (x=0.275 and 1/3)

Abstract:
We report neutron scattering measurements of the spectrum of magnetic excitations in the stripe-ordered phase of La2-xSrxNiO4 (x=0.275 and 1/3). The propagating spin excitations follow a similar dispersion relation for the two compositions, but the line widths are broader for x=0.275 than for x=1/3.
