The Haldane gap energies $Delta_x=0.42$ meV, $Delta_y=0.52$ meV and $Delta_z=1.86$ meV, for excitations polarized along the a, b, and c crystallographic axes, respectively, are directly measured. The dispersion perpendicular to the chain axis c is studied, and extremely weak inter-chain coupling constants $J_y=1.8cdot 10^{-3}$ meV and $J_x=3.5cdot 10^{-4}$ meV, along the a and b axes, respectively, are determined. The results are discussed in the context of future experiments in high magnetic fields. | | Source: | arXiv, cond-mat/0003223 | | Services: | Forum | Review | PDF | Favorites | |
