Spin excitations under fields in an anisotropic bond-alternating quantum S=1 chain: contrast with Haldane spin chains
M. Hagiwara, L. P. Regnault, A. Zheludev +8
Inelastic neutron scattering experiments on the S=1 quasi-one-dimensional bond-alternating antiferromagnet Ni(C9D24N4)(NO2)ClO4 have been performed under magnetic fields below and…
Magnetic excitations in the quantum spin system NH4CuCl3
A. Oosawa, T. Ono, K. Kakurai +1
NH4CuCl3 has two magnetization plateaus at one-quarter and three-quarters of the saturation magnetization, irrespective of the external field direction. Magnetic excitations in NH4…
Magnetic Excitations of the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +3
TlCuCl has a singlet ground state with the excitation gap meV. The magnetic excitations in TlCuCl have been investigated by means of neutron inelastic scattering e…
Magnetic Excitations in the Spin Gap System TlCuCl
A. Oosawa, T. Kato, H. Tanaka +5
Single-crystal neutron inelastic scattering was performed in order to investigate the magnetic excitations in the spin gap system TlCuCl. The constant- energy scan pro…
BaCu_2Si_2O_7: a new quasi 1-dimensional S = 1/2 antiferromagnetic chain system
I. Tsukada, Y. Sasago, K. Uchinokura +5
The new antiferromagnetic (AF) compound BaCu_2Si_2O_7 is studied by magnetic susceptibility and neutron scattering techniques. The observed behavior is dominated by the presence of…
