Correlated decay of triplet excitations in the Shastry-Sutherland compound SrCu(BO)
M. E. Zayed, Ch. Rüegg, Th. Strässle +8
The temperature dependence of the gapped triplet excitations (triplons) in the 2D Shastry-Sutherland quantum magnet SrCu(BO) is studied by means of inelastic neutron sc…
Proton diffusivity in the BaZr0.9Y0.1O3-δ proton conductor
Artur Braun, Sophie Duval, Peter Ried +7
The thermally activated proton diffusion in BaZr0.9Y0.1O3-δ was studied with electrochemical impedance spectroscopy (IS) and quasi-elastic neutron scattering (QENS) in the temperat…
Study of diffuse scattering under hydrostatic pressure in PbMg1/3Nb2/3O3
G -M Rotaru, B Padmanabhan, S N Gvasaliya +5
We report measurements of the evolution of the diffuse scattering in a single crystal PbMg1/3Nb2/3O3 as a function of hydrostatic pressure. Upon applying pressure the diffuse scatt…
Spin-state polaron in lightly hole-doped LaCoO_3
A. Podlesnyak, M. Russina, A. Furrer +8
Inelastic neutron scattering (INS), electron spin (ESR) and nuclear magnetic resonance (NMR) measurements were employed to establish the origin of the strong magnetic signal in lig…
Anomalous pressure dependence of the atomic displacements in the relaxor ferroelectric PbMgTaO
S. N. Gvasaliya, V. Pomjakushin, B. Roessli +3
The crystal structure of the PbMgTaO (PMT) relaxor ferroelectric was studied under hydrostatic pressure up to GPa by means of powder neutron diffractio…
