Magnetic excitations in the noncentrosymmetric magnet Sr2MnSi2O7
Masahiro Kawamata, Xiaoqi Pang, Hiroshi Murakawa +7
Magnetic excitations in the noncentrosymmetric magnet SrMnSiO were investigated through inelastic neutron scattering measurements. Major magnetic excitations are limite…
Emergent spin- Haldane gap and ferroelectricity in a frustrated spin- ladder
Hiroshi Ueda, Shigeki Onoda, Yasuhiro Yamaguchi +19
We report experimental and theoretical evidence that RbCuMoO has a nonmagnetic tetramer ground state of a two-leg ladder comprising antiferromagnetically coupled…
Spin Model of O2-based Magnet in a Nanoporous Metal Complex
M. Soda, Y. Honma, S. Takamizawa +3
Inelastic neutron scattering experiments are performed on a nanoporous metal complex Cu-Trans-1,4-Cyclohexanedicarboxylic Acid (Cu-CHD) adsorbing O2 molecules to identify the spin…
Development of spin correlations in the geometrically frustrated triangular-lattice Heisenberg antiferromagnet CuCrO2
R. Kajimoto, K. Tomiyasu, K. Nakajima +3
Magnetic excitations in the triangular-lattice Heisenberg antiferromagnet (TLHA) CuCrO2 were studied using single-crystal inelastic neutron scattering. A diffusive quasielastic com…
Spin-orbit fluctuations in frustrated heavy-fermion metal LiVO
K. Tomiyasu, K. Iwasa, H. Ueda +6
Spin fluctuations were studied over a wide momentum () and energy () space in the frustrated -electron heavy-fermion metal LiVO by time-of-flight inelastic n…
Spin nematic interaction in multiferroic compound BaCoGeO
M. Soda, M. Matsumoto, M. Mansson +4
We demonstrate the existence of the spin nematic interactions in an easy-plane type antiferromagnet BaCoGeO by exploring the magnetic anisotropy and spin dynamics…
Inelastic neutron scattering study of phonon anomalies in La1.5Sr0.5NiO4
R. Kajimoto, M. Fujita, K. Nakajima +4
The high-energy phonons in La1.5Sr0.5NiO4, in which the checkerboard charge ordering is formed, was investigated by the inelastic neutron scattering. We found that the longitudinal…
Dominance of excitation continuum in the longitudinal spectrum of weakly coupled Heisenberg S=1/2 chains
A. Zheludev, K. Kakurai, T. Masuda +2
A low-field spin flop transition in the quasi one-dimensional antiferromagnet \ba is exploited to study the polarization dependence of low-energy magnetic excitations. The measured…
