The magnetic state of Yb in Kondo-lattice YbNi2B2C

A. T. Boothroyd, J. P. Barratt, P. Bonville +4

We report neutron scattering experiments performed to investigate the dynamic magnetic properties of the Kondo-lattice compound YbNi2B2C. The spectrum of magnetic excitations is fo…

The pseudo-binary mercury chalcogenide alloy HgSe0.7S0.3 at high pressure: a mechanism of the zinc blende/cinnabar reconstructive phase transition

D. P. Kozlenko, K. Knorr, L. Ehm +4

The structure of the pseudo-binary mercury chalcogenide alloy HgSe0.7S0.3 has been studied by means of X-ray and neutron powder diffraction at pressures up to 8.5 GPa. A phase tran…

Evidence for weak itinerant long-range magnetic correlations in UGe2

A. Yaouanc, P. Dalmas de Reotier, P. C. M. Gubbens +4

Positive muon spin relaxation measurements performed on the ferromagnet UGe2 reveal, in addition to the well known localized 5f-electron density responsible for the bulk magnetic p…

A neutron scattering study of two-magnon states in the quantum magnet copper nitrate

D. A. Tennant, C. Broholm, D. H. Reich +7

We report measurements of the two-magnon states in a dimerized antiferromagnetic chain material, copper nitrate (Cu(NO3)2*2.5D2O). Using inelastic neutron scattering we have measur…

The Hydride Anion in an Extended Transition Metal Oxide Array: LaSrCoO_3H_{0.7}

M. A. Hayward, E. J. Cussen, J. B. Claridge +6

We present the synthesis and structural characterisation of a transition metal oxide hydride, LaSrCoO_3H_{0.7}, which adopts an unprecedented structure in which oxide chains are br…

Doping evolution of the phonon density of states and electron-lattice interaction in NdCeCuO

H. J. Kang, Pengcheng Dai, D. Mandrus +6

We use inelastic neutron scattering to study the evolution of the generalized phonon density of states (GDOS) of the -type high- superconductor NdCeCuO…
