Time-of-flight elastic and inelastic neutron scattering studies on the localized electron layered perovskite LaMoO
K. Iida, R. Kajimoto, Y. Mizuno +11
The magnetic structure and spin-wave excitations in the quasi-square-lattice layered perovskite compound LaMoO were studied by a combination of neutron diffraction a…
Nonlinear optical response and spin-charge separation in one-dimensional Mott insulators
Y. Mizuno, K. Tsutsui, T. Tohyama +1
We theoretically study the nonlinear optical response and photoexcited states of the Mott insulators. The nonlinear optical susceptibility χ^(3) is calculated by using the exact di…
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…
Electronic States and Excitation Spectra of Copper Oxides with Ladder and/or Chain
Yoshiaki Mizuno, Takami Tohyama, Sadamichi Maekawa
Recently the superconductivity has been reported in the copper oxides (Sr,Ca)CuO with ladders and edge-sharing chains under pressure. In order to understand th…
