We plan to perform transverse field and zero-field μSR experiments to investigate the temperature dependence of the relaxation rate in the superconducting phase of... -
muSR of Polyethylene Oxide: A Simple Proton-Conducting Polymer
Proton-conducting polymer membranes have significant technological applications in hydrogen or methanol fuel cells. muSR can shed light on the mechanisms for proton transport in... -
Muon states in black phosphorus
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... -
A second generation 2D antiferromagnet investigated with muons
Low-dimensional quantum magnetism continues to be of great theoretical and experimental interest, as reduced dimensionality supports strong quantum fluctuations which can result... -
Understanding the spin-Peierls Transition in KTCNQ and derivatives
Motivated by work showing that magnetic coupling between TCNQ anions in potassium TCNQ (KTCNQ) can be changed simply by changing the aromatic substituents, we seek to qunatify... -
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... -
Low Temperature Study of the Cluster Glass Phase in Ni(TCNQ)2
Recently there has been an M(TCNQ)2, where M=Mn, Co, Fe and Ni, series synthesised where all samples formed a stochiometric glassy ferromagnetic salt. We have focused on the... -

We propose to use longitudinal field muon-spin relaxation to investigate the excitation spectrum of the most successful realizations of one- and two-dimensional antiferromagnets... -
Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -

Cubic A2B2O7 oxides with A standing for a rare-earth element and B for a transition or main block metal have been systematically studied for their frequently exotic... -
Spin crossover and low temperature spin dynamics in In2VO5
The one dimensional material In2VO5 contains frustrated zigzag chains of corner sharing V 4+ (S = 1/2) square based pyramids interspersed with sheets of edge sharing InO6... -
Muon spin dynamics in ZnSe
We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is... -
Hunting for the low-temperature, low-field magnetization plateau in Tb2Ti2O7
Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the... -

In the present project we will focus on critical behaviour of Cu3(pyrazine)[W(CN)8]2 revealing magnetic phase transition at Tc=43 K. The findings will be compared to those... -
Muon Spin Relaxation and ALC Resonance in Magnetic and non-Magnetic Oxalate S...
Repolarisation and level crossing resonance will be studied for several different oxalate compounds where muon radical states are known to be formed. Such compounds form a... -

We are currently investigating Haldane spin-chain compounds [PRB 2017] of the type R2BaNiO5 (R = rare earth) using bulk measurements and have found the multifunctional... -
Possible muon diffusion in frustrated magnets
Recent investigations into spin ice suggest excitations that behave like magnetic monopoles, this has included a transverse field muon experiment. When zero field muon... -
Geometrical frustration induced magnetism in single crystal of CeIrSn: A Muon...
The quasi-kagome Kondo lattice CeRhSn exhibits quantum criticality induced by geometrical frustration. Divergent Grüneisen ratios provide evidence for a zero-field QCP. The... -
