Motion of Positevely Charged Muonium Centres in Transparent Conducting Oxides
We propose zero-field depolarization measurements to investigate the motional dynamics of diamagnetic muonium centers in hafnium oxide (HfO2), tungsten oxide (WO3) and zirconium... -
Motion of Positevely Charged Muonium Centres in Transparent Conducting Oxides
A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and... -
Structures of New Oxides from Total Scattering
Our objective is to determine accurate structural models for some novel oxide materials that we have recently prepared using new synthesis approaches, each of which is formed as... -
High Temperature Magnetic Order in Mn(II) Oxides
The Mn(II) phases LaSrMnO3.5 and LaBaMnO3.5 have been prepared by the topotactic reduction of LaSrMnO4 and LaBaMnO4 respectively. Preliminary neutron diffraction data show that... -
Fluorophosphate Derivatives of Gypsum and Lithium in Biogenic Manganese Oxides
This proposal seeks neutron diffraction beamtime to study two important systems. We have demonstrated that monofluorophosphate (PO3F) can be substituted into gypsum (CaSO4.2H2O)... -
Hydrogen Uptake by Pillared Graphite Oxides
High sorption capacities and enhanced interaction strengths are the two most fundamental prerequisites for the deployment of carbon-based materials as hydrogen-storage media. In... -
Structural Studies of Complex Mixed-Metal Pyrochlore and Spinel Oxides
Our objective is to determine structural models for some complex, mixed-metal oxide phases that are as complete as possible using analysis of PDFs produced from total neutron... -
Motion of Positively Charged Muonium Centres in Transparent Conducting Oxides
We propose further zero-field muon spin depolarization measurements at temperatures above 300K in order to determine barriers for thermal diffusion of positively charged muonium...
