27Al-NMR Study on a square-Kagome lattice antiferromagnet
Takayuki Goto, Masayoshi Fujihala, Setsuo Mitsuda
NMR study has been performed on an S = 1/2 antiferromagnet KCu6AlBiO4(SO4)5Cl on the square-Kagome lattice, which has three slightly inequivalent nearest-neighbor interactions. Bec…
Cluster-based Haldane state in edge-shared tetrahedral spin-cluster chain: Fedotovite KCuO(SO)
M. Fujihala, T. Sugimoto, T. Tohyama +13
Fedotovite KCuO(SO) is a candidate of new quantum spin systems, in which the edge-shared tetrahedral (EST) spin-clusters consisting of Cu are connected by we…
Tomonaga-Luttinger spin liquid in the spin-1/2 inequilateral diamond-chain compound KCuAlO(SO)
M. Fujihala, H. Koorikawa, S. Mitsuda +14
KCuAlO(SO) is a highly one-dimensional spin-1/2 inequilateral diamond-chain antiferromagnet. Spinon continuum and spin-singlet dimer excitations are observed in…
Static and Dynamic Magnetic Properties of Spin-1/2 Inequilateral Diamond-Chain Compounds CuAlO(SO) (=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…
Spin-Driven Bond Order in a 1/5-Magnetization Plateau Phase in a Triangular Lattice Antiferromagnet CuFeO2
Taro Nakajima, Noriki Terada, Setsuo Mitsuda +1
We have investigated spin-wave excitations in a magnetic-field-induced 1/5-magnetization plateau phase in a triangular lattice antiferromagnet CuFeO2 (CFO), by means of inelastic n…
Magnons and electromagnons in a spin-lattice-coupled frustrated magnet CuFeO2 as seen via inelastic neutron scattering
Taro Nakajima, Azusa Suno, Setsuo Mitsuda +4
We have investigated spin-wave excitations in a four-sublattice (4SL) magnetic ground state of a frustrated magnet CuFeO2, in which `electromagnon' (electric-field-active magnon) e…
