Inelastic neutron scattering study on the AFM uniform spin-1/2 chain compound CuSb2O6
Masashi Hasea, Minoru Soda, Takatsugu Masuda +2
We carried out inelastic neutron scattering experiments on a powdered sample of the antiferromagnetic (AFM) uniform spin-1/2 chain compound CuSb2O6.The magnetic excitations appear…
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…
Low-Energy Excitations and Ground State Selection in Quantum Breathing Pyrochlore Antiferromagnet BaYbZnO
T. Haku, K. Kimura, Y. Matsumoto +10
We study low energy excitations in the quantum breathing pyrochlore antiferromagnet BaYbZnO by combination of inelastic neutron scattering (INS) and thermodynami…
Experimental confirmation of spin gap in antiferromagnetic alternating spin-3/2 chain substances RCrGeO5 (R = Y or 154Sm) by inelastic neutron scattering experiments
M. Hase, M. Soda, T. Masuda +6
A spin-singlet ground state with a spin gap has been discovered in antiferromagnetic spin chain substances when the spin value is 1/2, 1 or 2. To find spin gap (singlet-triplet) ex…
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…
Correlation between spin helicity and electric polarization vector in quantum-spin chain magnet LiCuO
S. Seki, Y. Yamasaki, M. Soda +3
Measurements of polarized neutron scattering were performed on a chain multiferroic LiCuO. In the ferroelectric ground state with the spontaneous polarization along…
