Abstract
A metal-organic compound 2Dioxane ⋅2 H₂O⋅CuCl₂ has been synthesized and structurally characterized by x-ray crystallography. Magnetic susceptibility and zero-field inelastic neutron scattering have also been used to study its magnetic properties. It turns out that this material is a weakly coupled one-dimensional S= 1/2 Heisenberg antiferromagnetic chain system with chain direction along the crystallographic c axis and the nearest-neighbor intrachain exchange constant J=0.85 (4) meV. The next-nearest-neighbor interchain exchange constant J′ is also estimated to be 0.05 meV. The observed magnetic excitation spectrum from inelastic neutron scattering is in excellent agreement with numerical calculations based on the Müller ansatz. © 2009 The American Physical Society.
