Spin glass behaviour in the disorder-free geometrically frustrated magnet Yb2...
Our susceptibility studies of the frustrated magnet Yb2Sn2O7 has revealed a spin glass transition of the Yb3+ magnetic lattice at T_g = 140 mK. To our knowledge, this... -
Comparative study of magnetic Skyrmion formation in Co-Mn-Zn alloys
Skyrmions are topologically protected vortex-like spin textures, and have been attracting increasing attention due to their potential technological applications for spintronics.... -
Muonium in widegap oxides
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... -
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... -
µSR studies of the superconducting and magnetic properties of FeSe1-xSx
FeSe1-xSx is an important model system for investigating the relationship between superconductivity and nematicity. The nematicity can be suppressed systematically by the... -
Investigating spin dynamics in spinel spin ice with musr and high freqeuncy s...
Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of... -
Longitudinal relaxation measurements in the ferromagnetic phase of the superc...
We aim to perform zero and longitudinal field muon spin relaxation measurements in order to investigate anomalous spin dynamics effects observed in EuFe2(As1-xPx)2 with x=0.20... -

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... -
Observation of hydrogen dynamics in hydrogen storage materials by muSR
Hydrogen storage materials with a low working temperature are strongly required for the application of the next generation on-board hydrogen storage system. Among several... -
Investigating the nature of magnetism by μSR study in the Kondo-lattice ...
Ce-compounds are well known to present very rich physics and exotic electronic ground state due to the competing RKKY, Kondo and crystal field interactions. Recently CeRuPO... -
Spectroscopy of muon centres in n-type silicon carbide
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... -

Li diffusion in charged state Lix(Ni1/3Co1/3Mn1/3)O2
This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a... -
Total Scattering Study of Caesium and Thallium Azides
This proposal seeks to conduct total-scattering studies on thallium and caesium azides to investigate the effect of temperature on the atomic motions, particularly of the azide... -
Direct measurement of magnetoelectric coupling - a new room temperature multi...
We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field... -
Quantum criticality in the Kitaev system alpha-RuCl3
The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics because the model uniquely provides exactly solvable... -
Field-induced low-temperature magnetic phase in alkali-metal sesquioxides
Open p-shell anionic compounds are model systems where the interplay between charge, lattice, orbital, and spin degrees of freedom leads to complex magnetic behavior. In the... -
