Frustration, quantum spin ices and quantum diffusion
This proposal aims to characterise the spin dynamics of three Pr-based pyrochlores that may be realisations of quantum spin ice materials. The lower moment and larger wave... -
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... -
Vibrations of a muoniated radical center and photochemistry in benzophenone
Benzophenone is an ideal material to study vibrations of a muon radical centre with near-IR laser light, as all C=O bonds in solid state are almost parallel to each other and it... -

μSR Study of the B20 superconductor AuBe
In conventional superconductors inversion symmetry plays an important role in Cooper pair formation. The discovery of superconductors lacking inversion symmetry... -
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... -

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... -
Spin correlations of a triangular-lattice quantum-spin-liquid candidate
A quantum spin liquid (QSL) shows no magnetic order down to zero temperature but the spins are highly entangled. More and more interests are attracted to 2D spin-1/2... -
