Microstructure and thermal properties of unalloyed tungsten deposited by Wire + Arc Additive Manufacturing
Gianrocco Marinelli, Filomeno Martina, Supriyo Ganguly +5
Tungsten is considered as one of the most promising materials for nuclear fusion reactor chamber applications. Wire + Arc Additive Manufacturing has already demonstrated the abilit…
Magnetic excitation spectrum of LuFe2O4 measured with inelastic neutron scattering
S. M. Gaw, H. J. Lewtas, D. F. McMorrow +7
We report neutron inelastic scattering measurements and analysis of the spectrum of magnons propagating within the Fe2O4 bilayers of LuFe2O4. The observed spectrum is consistent wi…
Magnetic excitations in multiferroic LuMnO3 studied by inelastic neutron scattering
H. J. Lewtas, A. T. Boothroyd, M. Rotter +6
We present data on the magnetic and magneto-elastic coupling in the hexagonal multiferroic manganite LuMnO3 from inelastic neutron scattering, magnetization and thermal expansion m…
Muon-spin relaxation and heat capacity measurements on the magnetoelectric and multiferroic pyroxenes LiFeSi2O6 and NaFeSi2O6
P. J. Baker, H. J. Lewtas, S. J. Blundell +6
The results of muon-spin relaxation and heat capacity measurements on two pyroxene compounds LiFeSi2O6 and NaFeSi2O6 demonstrate that despite their underlying structural similarity…
Local magnetism and magnetoelectric effect in HoMnO3 studied with muon-spin relaxation
H. J. Lewtas, T. Lancaster, P. J. Baker +3
We present the results of muon-spin relaxation (muSR) measurements on the hexagonal manganite HoMnO3. Features in the temperature-dependent relaxation rate, lambda, correlate with…
Spin freezing and dynamics in Ca_{3}Co_{2-x}Mn_{x}O_{6} (x ~ 0.95) investigated with implanted muons: disorder in the anisotropic next-nearest neighbor Ising model
T. Lancaster, S. J. Blundell, P. J. Baker +5
We present a muon-spin relaxation investigation of the Ising chain magnet Ca_{3}Co_{2-x}Mn_{x}O_{6} (x~0.95). We find dynamic spin fluctuations persisting down to the lowest measur…
