摘要：

An effective Hamiltonian is constructed for an insulating cuprate with edge-sharing chains Li2CuO2 The Hamiltonian contains the nearest and next-nearest neighboring intrachain and zigzag-type interchain interactions. The values of the interactions are obtained from the analysis of the magnetic susceptibility, and this system is found to be described as coupled frustrated chains. We calculate the dynamical spin correlation function S(q,w) by using the exact diagonalization method, and show that the spectra of S(q,w) are characterized by the zigzag-type interchain interactions. The results of the recent inelastic neutron-scattering experiment are discussed in the light of the calculated spectra. [S0163-1829(99)11133-0].
