Abstract

Quasielastic magnetic neutron scattering from the linear-chain antiferromagnet ${(C D_{3})}_{4}$ NMn ${Cl}_{3}$ is reported. The system is found to exhibit planes of critical scattering perpendicular to the Mn ${Cl}_{3}$ chains from >40°K down to 1.1°K. Both the spatial and thermal variation of the scattering can be quantitatively accounted for at all temperatures using Fisher's theory for the classical Heisenberg linear chain.
