Systematic Study of Magnetic Interactions in Insulating Cuprates
Yoshiaki Mizuno, Takami Tohyama, Sadamichi Maekawa
The magnetic interactions in one-dimensional, two-dimensional (2D) and ladder cuprates are evaluated systematically by using small Cu-O clusters. We find that the superexchange int…
Magnetic Interaction in Insulating Cuprates
Yoshiaki Mizuno, Takami Tohyama, Sadamichi Maekawa
We examine two-spin (2S) and cyclic four-spin (4S) magnetic interactions in insulating ladder and two-dimensional (2D) cuprates. By a comparison of eigenstates between d-p and Heis…
Interchain interactions and magnetic properties of Li2CuO2
Y. Mizuno, T. Tohyama, S. Maekawa
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…
