Stability of charge-stripe ordered La2-xSrxNiO4+delta at one third doping
P. G. Freeman, R. A. Mole, N. B. Christensen +2
The stability of charge ordered phases is doping dependent, with different materials having particularly stable ordered phases. In the half filled charge ordered phases of the cupr…
Direct evidence for charge stripes in a layered cobalt oxide
P. Babkevich, P. G. Freeman, M. Enderle +2
Recent experiments indicate that static stripe-like charge order is generic to the hole-doped copper oxide superconductors and competes with superconductivity. Here we show that a…
Zn-induced spin dynamics in overdoped LaSrCuZnO
Stephen D. Wilson, Z. Yamani, Chetan Dhital +7
Spin fluctuations and the local spin susceptibility in isovalently Zn-substituted LaSrCuZnO (, ) are measured via inelastic neut…
Evidence of Magnetic Correlations Among the Charge Stripe Electrons of Charge-Stripe Ordered La2NiO4.11
P. G. Freeman, S. M. Hayden, R. A. Mole +3
The magnetic excitations of charge-stripe ordered La2NiO4.11 where investigated using polarized- and unpolarized-neutron scattering to determine the magnetic excitations of the cha…
Spin anisotropy of the resonance in superconducting FeSe0.5Te0.5
P. Babkevich, B. Roessli, S. N. Gvasaliya +5
We have used polarized-neutron inelastic scattering to resolve the spin fluctuations in superconducting FeSe0.5Te0.5 into components parallel and perpendicular to the layers. A spi…
Anisotropic Neutron Spin Resonance in Superconducting BaFeNiAs
O. J. Lipscombe, Leland W. Harriger, P. G. Freeman +8
We use polarized inelastic neutron scattering to show that the neutron spin resonance below in superconducting BaFeNiAs ( K) is purely magnetic in…
Stripe Order and Magnetic Transitions in La(2-x)Sr(x)NiO(4)
P. G. Freeman, A. T. Boothroyd, D. Prabhakaran +2
Magnetic order has been investigated in stripe-ordered La(2-x)Sr(x)NiO(4) (x = 0.275, 0.37, 0.4) by d.c. magnetization and by polarized- and unpolarized-neutron diffraction. In the…
Magnetization of Charge-ordered la(2-x)sr(x)nio(4+delta)
P. G. Freeman, A. T. Boothroyd, D. Prabhakaran +1
We report magnetization measurements on La(2-x)Sr(x)NiO(4+ delta) single crystals, with 0 < x < 0.5. Glassy behaviour associated with the formation of spin-charge stripes, and a se…
Spin reorientation transition in the incommensurate stripe-ordered phase of La3/2Sr1/2NiO4
P. G. Freeman, A. T. boothroyd, D. Prabhakaran +2
The spin ordering of La3/2Sr1/2NiO4 was investigated by magnetization measurements, and by unpolarized- and polarized-neutron diffraction. Spin ordering with an incommensurability…
