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... -
Spin dynamics in the ground state of the multiferroic FeTe2O5Br and FeTe2O5Cl
Recently, we have found a new multiferroics material FeTe2O5Br, with simultaneous ferroelectric and incommensurate magnetic orderings appear at TN = 11 K. Our neutron... -
A µSR study of single crystals of the superconductor FeSe1 xTex (0≤x...
Superconductivity was recently discovered in alpha-phase FeSex with a Tc of 8 K. Selenium can be replaced with Tellurium (FeSe1-xTex) and this results in an increase in Tc to 15... -
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... -
Systematic Investigation of Magnetically Doped Toplogical Insulators
Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped... -
Spin dynamics and magnetic ordering in the p-orbital molecular solids CsO2 an...
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... -
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... -

µSR investigations of magnetoelectric 4d-based dimer system Ba3NdRu2O9
The magnetic ground state of a compound containing higher d-orbital (4d/5d) is fascinating due to its various competing effects like extended orbital, pronounced crystal field... -
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... -

In recent times iridates have become a fertile ground for studies of new physics driven by strong spin-orbit coupling that is analogous to the on-site Coulomb and crystalline... -
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... -
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... -
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... -
Spin dynamics of Ce in the Noncentrosymmetric Heavy-Fermion Superconductors C...
In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have... -
