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)... -
Probing the [FeFe]-hydrogenase using muon spectroscopy
During our previous experiment on HiFi (RB1320541) we measured the ALC spectrum of the Fe2(µ-pdt)(CO)4(PMe3)2 model hydrogenase complex over multiple temperatures. The spectra... -
Temperature and environment dependence of the isotope effect in muonated radi...
We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a... -
Muon states and diffusion in alkali halides
The diamagnetic states formed by muon implantation in alkali halides are to be characterised, and their diffusion studied, by means of RF final-state analysis. The 90° pulse... -
