Diffuse scattering in the paraelectric phase of titanite
Titanite consists of TiO6 octahedra arranged in chains. These are linked by SiO4 tetrahedra. At room temperature, Ti is slightly off-center resulting in an alternation of short... -
Dynamic Nuclear Polarization in GaAs by electrical spin injection
We propose to measure the dynamic nuclear polarization in a GaAs-based structure caused by electrical injection of a spin-polarized current using polarized neutron... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism... -
Neutron scattering from topological magnetic structures in Fe1-xCoxSi
FeSi is a member of the transition metal (TM) monosilicides. The crystal structure is isostructural from MnSi through to CoSi with magnetic properties that alter dramatically... -
FePS3 magnetic and crystal structure under pressure
We have metallised the two-dimensional honeycomb anti-ferromagnet FePS3 at 5.5 GPa. The mechanisms for metallisation, as well as the physical properties of the metallic state,... -
Spin dynamics in FeSi
At low temperatures FeSi is a non-magnetic insulator, but becomes a metallic paramagnet for T > 300K. It has been proposed to be a Kondo insulator in which local electron... -
The icy-moon analogue of MgSiO3-perovskite: MgSO4.9H2O a high-pressure study
Mg-sulfate 11-hydrate (meridianiite) is decomposed by pressure to form Mg-sulfate 9-hydrate + ice, a process that will occur in the mantles of large icy planetary bodies and...
