We propose zero-field depolarization measurements to investigate the motional dynamics of diamagnetic muonium centers in hafnium oxide (HfO2), tungsten oxide (WO3) and zirconium...

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...

We propose RF-MuSR experiments focused on confirming the two shallow Mu donor states tentatively observed in single crystalline beta-Ga2O3 samples. This material is a candidate...

Single crystal, bulk Si1-xGex alloys are available across the alloy composition range, and provide opportunity for study of alloy properties in transition between the two...

Our group has been working partially oxidized cellulose nanofibrils which form gels in aqueous formulations. Recently we have observed that these fibrils also gel when dialysed...

We propose to determine temperature dependent diffusion parameters of positively charged muonium centres in w-ZnO. Specifically, we would like to exploit the zero field tools to...

We propose longitudinal muon spin depolarization measurements to extract the energy for the T-site Mu acceptor level in mid-range SiGe alloys where a direct determination of the...

In recent work with Unilever we have been investigating the structure of gels formed by partially oxidised cellulose nanofibrils for use in sustainable personal care products....

We propose to obtain the detailed temperature dependent diffusion characteristics for diamagnetic muonium defect centres, assumed to be a 'bare' muon, in selected members of the...

We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu...

Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above...

We propose a continuation of longitudinal muon spin depolarization measurements on mid-range SiGe alloys where a direct observation of T-site ionization is not possible because...

The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of...

Rutile titanium dioxide is one of the most relevant oxide materials, where the impurity physics of hydrogen has recently been devoted much attention. Existing ab-initio...

We propose a MuSR study of the magnetism in Mn-doped ZnGeP2 during this round of experiments using muon spin depolarization measurements in a longitudinal magnetic field. This...

We propose an investigation of the magnitude and fluctuations of internal magnetic fields in Mn-doped ZnGeP2. This chalcopyrite structured semiconductor has a ferromagnetic (FM)...

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...
