We ask for 3 days on EMU to study the Muon spectroscopy of both LiBH4 and Ca(BH4)2 as a function of temperature from 90K-650K. These materials have been extensively...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...

The great majority of known muonium defect centres and muonium substituted organic radicals have essentially spin-only magnetism, with few exhibiting any noticeable departure...

The ambient-pressure Pnma phase of NiSi is a technologically important material used to form contacts in microelectronics. Recently we carried out the first study of NiSi at...

Following our investigation of alpha-orthorhombic sulphur, we will measure level crossing spectra of some other allotropes and phases, to find if the muon radical observed in...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

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...

Experiment is proposed to identify magnetic polaron bound to the muon using RF-muSR. In recent experiment at TRIUMF magnetic polaron was found in transverse field and its...

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,...

The usual assumption that the muon's polarisation relaxes to zero at long times may be incorrect at high B and low T: for 5T and 30mK the Brillouin function gives P=49%. We plan...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...

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...

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...

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

Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with...

The elusive OMu radical is believed to be formed by muonium reaction with nitrous oxide but has never been directly observed. It would be invisible to transverse-field muon spin...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...

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...

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...

Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution....
