Magnetization plateaus in the spin-1/2 antiferromagnetic Heisenberg model on a kagome-strip chain

K. Morita, T. Sugimoto, S. Sota +1

Spin-1/2 Heisenberg model on kagome lattice is a typical frustrated quantum spin system. A basic structure of kagome lattice is also present in kagome-strip lattice in one dimensio…

Observation of a dispersive charge mode in hole-doped cuprates using resonant inelastic x-ray scattering at the oxygen K edge

K. Ishii, T. Tohyama, S. Asano +13

We investigate electronic excitations in La2-x(Br,Sr)xCuO4 using resonant inelastic x-ray scattering (RIXS) at the oxygen K edge. RIXS spectra of the hole-doped cuprates show clear…

Static and Dynamic Magnetic Properties of Spin-1/2 Inequilateral Diamond-Chain Compounds $A_{3}$ Cu $_{3}$ AlO $_{2}$ (SO $_{4}$ ) $_{4}$ ( $A$ =K, Rb, and Cs)

Katsuhiro Morita, Masayoshi Fujihala, Hiroko Koorikawa +4

Spin-1/2 compounds A3Cu3AlO2(SO4)4 (A=K, Rb, and Cs) have one-dimensional (1D) inequilateral diamond chains. We analyze the temperature dependence of the magnetic susceptibility an…
