title = "Anisotropic spin excitations in spin-Peierls CuGeO3",
abstract = "We report on the investigation of spin excitations in CuGeO3 at a low temperature by using inelastic neutron scattering on a pulsed source with a time-of-flight analysis. By observing the dispersion relation of spin excitations not only along the chain direction but also along the inter chain direction, we studied spin correlations in the S = 1/2 Heisenberg chains, as well as between the chains, in detail. The results show a clear anisotropy of the magnetic excitations at a temperature below the spin-Peierls transition temperature.",
