FeSe1-xSx is an important model system for investigating the relationship between superconductivity and nematicity. The nematicity can be suppressed systematically by the...

The [FeFe]-hydrogenase enzymes are some of the best catalysts know for generating hydrogen. We have an ongoing programme to understand how their chemistry works, and to...

The investigation of electron correlations in intermetallic alloys is fascinating. At times, depending on the nature and strength of correlations, the compounds exhibit...

This is a continuation proposal, for work carried out previously on the EMU and MuSR spectrometers. We have determined that spin fluctuations are present in this system, by...

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...

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...

Quadrupolar level crossing resonance (QLCR) occurs in the muSR of solids with diamagnetic muon states in close proximity to quadrupolar nuclei. This effect provides uniquely...

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...

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...

Our ability to control the synthesis of this kind of material has led to the development of a family of Ru-Ru-M-backbone organometallic compounds with general formula...

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...

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...

We propose a series of measurements to complete the previous direct spectroscopic measurements of the Muonium defect energy levels in Silicon Carbide (SiC; RB110134). We will...

Nearly all polymers form glasses and the glass transition at temperature Tg dominates many physical properties of polymers that are relevant for their applications. The most...

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

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...

Recently, we have found a new multiferroics material FeTe2O5Br, with simultaneous ferroelectric and incommensurate magnetic orderings appear at TN = 11 K. Our neutron...

The rise of quantum materials observed in the past decades has been a source of great excitement for condensed matter scientists, with the flourishing of new concepts and...

LiOsO3 is a very unusual metallic ferroelectric. This experiment aims to distinguish between two contrasting possibilities for the ground state of this material which can be...

The most successful recipe to date for making a quantum spin liquid (QSL) is a triangular lattice of molecular-dimer radicals tuned to behave as a weak Mott insulator. Two...
