Laser-induced electron transfer in Trp-Tyr
We wish to perform longitudinal field measurements on the dipeptide Trp-Tyr under laserexcitation, to probe the electron transfer process within the molecule. We have already... -
Investigation of excitonic physics in polycyclic aromatic hydrocarbon molecules
The MuSES project currently ongoing in the HiFi spectrometer gives unique opportunity in the field of photochemistry and photophysics of organic molecules. After two successful... -
Superconducting intercalates of FeSe tuned in situ with ammonia
We propose to study two phases of Na-NH3 intercalated FeSe which have distinct values of Tc, both close to 40 K, but different concentrations of NH3 and quite distinct crystal... -
Varying oxygen content in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen stoichiometry. Most... -

We plan to perform transverse field and zero-field μSR experiments to investigate the temperature dependence of the relaxation rate in the superconducting phase of... -
How complex is complex: an ALC study of a 10-mer helical peptide chain
There have been ALC studies on the interaction of muons with native proteins, but little systematic work that contributes understanding of how spectroscopic information alters... -
Valence bond solid in the charge ordered state of Rb4O6
Open p-shell anionic mixed-valence compounds have been recently proposed as intriguing model systems for disentangling the complex interplay of charge, lattice, orbital, and... -
Probing the Magnetism and Suspected Quantum Fluctuations in Green Dioptase
It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this... -

Our first completed photo-musr experiment on 6,13-bis(tri-iso propylsilylethynyl) pentacene (TIPS-Pn) has recently been accepted for publication. We observed a significant... -
Field-induced low-temperature magnetic phase in alkali-metal sesquioxides
Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the... -
Spin dynamics and magnetic ordering in the p-orbital molecular solids CsO2 an...
A magnetic response of the alkali-metal superoxides comes from the p-orbital S = 1/2 spins of anionic O2- molecules. As the O2- molecules are highly reorientable and the... -

BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
Field-induced low-temperature phase in NaO2
Molecular solids like sodium superoxide NaO2 exhibit intricate magnetic behavior despite their simple chemical structure. This is due to the interplay of spin, orbital and... -
