Abstract:

Inelastic neutron scattering measurements have been performed, for the first time, on a large, high quality single-crystal of PrBa2Cu3O6+x. Two relatively broad peaks are observed, the one at lower energy showing significant dispersion in the basal plane. Neither feature is observable above the Pr ordering temperature. The pressure dependence of the Cu and Pr ordering temperatures up to 1.75 GPa has also been determined. (C) 1999 Elsevier Science B.V. All rights reserved.
