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…
Helimagnetism in a disordered and geometrically frustrated quantum spin chain
T. Masuda, A. Zheludev, A. Bush +2
Neutron diffraction and bulk measurements are used to determine the nature of the low-temperature ordered state in LiCuO, a spin-chain compound with competing inter…
Spin dynamics in the weakly-coupled chains antiferromagnet BaCuSiO
A. Zheludev, M. Kenzelmann, S. Raymond +3
Inelastic neutron scattering is used to identify single-particle and continuum spin excitations in the quasi-one-dimensional antiferromagnet \ba. In the data analysis, clos…
Quantum and classical dynamics in complex one-dimensional antiferromagnets
A. Zheludev, S. Maslov, T. Yokoo +3
Of great recent interest in condensed matter physics are phenomena of coexistence of quantum and classical properties in the same material. Such duality occurs in certain mixed-spi…
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…
