摘要：

A polarised neutron scattering experiment has been performed on a single-Q, single domain sample of Cr in a magnetic field of 4 T in the transverse spin-density-wave phase. It is confirmed that the longitudinal fluctuations are enhanced for energy transfers E < 8 meV similarly as in the longitudinal spin-density-wave phase. The transverse modes with delta S parallel and perpendicular to Q are isotropic within the E-range investigated. (C) 1998 Elsevier Science B.V. All rights reserved.
