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 usin

©2015 American Physical Society. An inelastic neutron scattering study of the spin waves corresponding to the stripe antiferromagnetic order in insulating Rb0.8Fe1.5S2 throughout the Brillouin zone is reported. The spin wave spectra are well describ

Spin waves and electronic interactions in La2CuO4

Autor: Coldea, R, Hayden, SM, Aeppli, G, Perring, TG, Frost, CD, Mason, TE, Cheong, SW, Fisk, Z

The magnetic excitations of the square-lattice spin-1/2 antiferromagnet and high-Tc parent La2CuO4 are determined using high-resolution inelastic neutron scattering. Sharp spin waves with absolute intensities in agreement with theory including quantu
