Description

The magnetic excitation of the spin gap system KCuCl3 was studied using the neutron inelastic scattering technique. The dispersion curves along the diagonal directions in the a* -c* plane such as (h, 0, ±2h+1) were experimentally determined in detail. This enabled to choose the function for the best fitting uniquely and to obtain highly reliable fitting parameters, i.e., the inter-dimer interactions in KCuCl3 in the random phase approximation. The exchange network in the (102-bar) plane was found to be more important than the coupling along the double-chain. (author)
