Low Temperature muSR of the 2D Triangular Lattice Spin-Liquid System kappa-ET...
k-ET_2Cu_2(CN)_3 provides an excellent experimental system for studying the 2D S=1/2 frustrated triangular lattice Heisenberg model. A spin-liquid state persists in this system... -
High Temperature Spin Transition in LaCoO3
We aim to continue our investigation of the high temperature magnetic interactions in LaCoO3. Our previous experiment has confirmed magnetic susceptibility data, with a change... -
Quantum State Manipulation in PTFE.
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... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
Thermal ionization of bond-centred muonium in diamond
Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was... -
A µSR stoichiometry study of TixV1-x alloys superconductivity in the presen...
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... -
Quantum Spin Liquid in triangular Seff=1/2 rare-earth based antiferromagnets
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... -
Determining the ground state in the metallic ferroelectric LiOsO3
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... -
Spin Dynamics in the Quantum Critical and Ferromagnetic Regimes of URu2-xRe
Recently, there has been a significant amount of interest in quantum phase transitions and non-Fermi liquid (NFL) behavior exhibited by heavy-fermion compounds. Interestingly... -
Quantum Spin Liquid in a triangular rare-earth based magnet
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... -
Investigation of magnetic defects in exfoliated graphite
Graphene has recently received widespread attention, after the discovery of its stability as a 2Dcrystal at ambient conditions and thanks to a wealth of possible applications.... -
Motional Dynamics of Positively Charged Muonium in Anatase, Brookite and Ruti...
We propose a series of measurements on anatase and brookite Titanium Dioxide (TiO2) to investigate the motional dynamics of positively charged Mu centres and their transition... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and...
