Multiplexing Capabilities of Cold-Neutron Triple-Axis Spectrometer SIKA
Guochu Deng, Peter Vorderwisch, Garry J McIntyre
SIKA, a high-flux cold-neutron triple-axis spectrometer at the OPAL reactor at the Australian Nuclear Science and Technology Organization, is equipped with a 13-blade analyser and…
Field-driven phase transitions in a quasi-two-dimensional quantum antiferromagnet
M. B. Stone, C. Broholm, D. H. Reich +4
We report magnetic susceptibility, specific heat, and neutron scattering measurements as a function of applied magnetic field and temperature to characterize the quasi-two-…
Observation of Phasons in Magnetic Shape Memory Alloy Ni2MnGa
S. M. Shapiro, P. Vorderwisch, K. Habicht +2
An inelastic neutron scattering study of the lattice dynamics of the martensite phase of the ferromagnetic shape memory alloy, Ni2MnGa, reveals the presence of well-defined phasons…
Three-dimensionality of field-induced magnetism in a high-temperature superconductor
B. Lake, K. Lefmann, N. B. Christensen +9
Many physical properties of high-temperature (high-Tc) superconductors are two-dimensional phenomena derived from their square planar CuO2 building blocks. This is especially true…
Quantum Criticality in an Organic Magnet
M. B. Stone, C. Broholm, D. H. Reich +3
Exchange interactions between sites in piperazinium hexachlorodicuprate produce a frustrated bilayer magnet with a singlet ground state. We have determined the fiel…
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…
