Mapping spin-wave dispersions in stripe-ordered La2-xSrxNiO4 (x=0.275, 0.333)
Using the MAPS spectrometer at the ISIS spallation source, we have measured the magnetic excitations of single-crystal samples of stripe-ordered La2-x Srx Ni O4 with x=0.333 and 0.275. The full two-dimensional spin-wave dispersions were obtained using incident energies of 60 and 160 meV. To analyze...
