Abstract
Spin-wave branches in antiferromagnetic Pr2CuO4 have been followed up to en ergy of 200 meV using a three-axis neutron spectrometer. Progressive broade ning of the measured signal is observed with no signal detected at higher m agnon energies. (C) 2001 Elsevier Science B.V. All rights reserved.
