Abstract
Some experiments related to the quantum nature of spins that strongly manifest itself in the quasi-one-dimensional antiferromagnets are discussed with a reference to CsNiCl3 and related compounds. In particular, the field dependence of the low-temperature staggered magnetization that is substantially reduced by zero-point motion of spins was measured by neutron diffraction and is shown to account for the nonlinear homogeneous susceptibility. We also present a comparison between the spin dynamics of S=1 CsNiCl3 and S=5/2 CsMnBr3 above their Néel ordering temperatures measured by inelastic neutron scattering. It provides another spectacular evidence of the fundamental difference between the chains of integer and half-integer spins predicted by Haldane.
