This study involves attempting to understand the Li atom diffusion within Li-intercalated hexagonal boron nitride. Muons present a significant advantage as they are sensitive to...

In view of the interesting magnetic properties observed in CeTSi3 (T=Pt and Pd) and superconductivity in LaPdSi3 (TSC= 2.6 K), as well as the theoretical interest in...

Discrete energy level form in quantum mechanical systems and if carefully measured the population density of the levels can be probed and manipulated. The consequence of this...

At low temperatures and high magnetic fields, the electron in a muonium or radical state may be polarised if it has an opportunity to reach thermal equilibrium. Such a...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

We propose to characterise selected radical structures of the green-tea anti-oxidant flavenoid EGCG (& selected analogues), by DFT/post-HF computation and ALC-MuSR, towards...

In this proposal we intend to complete the characterization of the hydrogen impurity in solar cell materials Cu2ZnSnS4 (CZTS) and Cu(In,Ga)Se2 (CIGS), by using the positive...

Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we...

Radio Frequency µSR provides a direct method for accurately determining muon hyperfine coupling constants, Aµ, for muoniated radical species. The method complements the well...

We have recently performed a test experiment which demonstrates the potential (RB1510281) of using RF muon spectroscopy to manipulate the population of the levels of the FmuF...

This experiment addresses the study of electron transport in zinc-hexadecafluoro-phthalocyanine (F16-ZnPc), a model n-type phthalocyanine employed in organic electronics, using...

Understanding of chemical reactivity is founded on the fundamental concepts of Electrophilicity and Neucleophilicity. All extant attempts to do this depend on the reaction of...

Muon interactions with quadrupolar nuclear spins have occasionally been studied by theirlevel crossing resonance spectra. In an ideal case the quadrupole resonance level...

Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest, as reduced dimensionality supports strong quantum fluctuations which can result...

This proposal is part of a long-range program aiming at determining the stable charge-state configurations, site and impurity energy levels (donor and/or acceptor) of hydrogen...

We propose to use longitudinal field muon-spin relaxation to investigate the excitation spectrum of the most successful realizations of one- and two-dimensional antiferromagnets...

Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

The recovery of the muon polarization in a longitudinal magnetic field has been used to obtain the muon hfcs of organic radicals. In pure benzene there is a single step in the...

Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a...
