Abstract
The in-plane energy gap in the copper spin-wave excitation spectrum of the insulating antiferromagnet Pr2CuO4 has been studied by neutron inelastic sc attering. The magnitude and temperature dependence of the gap is related to the independently determined critical magnetic field of the spin reorienta tion transition. (C) 1999 Elsevier Science B.V.
