Abstract

To study the average value of the chirality in helically polarized antiferromagnets below T-N, the interaction of the chirality with elastic torsion has been exploited for a preferable population of one kind of chiral domains in Ho. For the investigation of chiral fluctuations above T-N a dynamical chirality (DC) which is the projection of the chiral held on the induced sample magnetization has been studied with polarized neutrons. For the first time the completely inelastic spin-dependent cross-section has been observed in CsMnBr3 and shown to be an odd function of the energy transfer as theoretically predicted. Spin-dependent chiral scattering has also been found for the spin waves in the magnetically ordered region of CsMnBr3. (C) 1999 Published by Elsevier Science B.V. All rights reserved.
