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... -
Detailed investigation of the magnetic interaction as a function of temperature
In the series R2PdSi3,the Nd compound is considered to be an anomalous as it orders ferromagnetically (TC= 16 K) with a weak frequency-dependent ac susceptibility (χ)... -
Engineering exchange strength in S=1/2 molecule-based magnets
Recent progress in the field of molecular magnetism has shown the potential for gaining control over the structural building blocks of molecular materials in order to engineer... -
Magnetic Ordering in the Heavy Fermion CePtZn
In rare-earth containing metals, there is a strong competition between the tendency of these systems to magnetically order or form a superconducting state, mirroring in many... -
Probing the spin dynamics in the pseudo-quaternary Y1-xErxNi2B2C compounds
Our uSR measurements on superconducting Y1-xErxNi2B2C shows a slowing of the Er spin dynamics upon cooling to 2.5 K, but the depolarisation rate does not critically diverge and... -
The search and optimisation of Delta0 resonances in TIPS-Pentacene in solution
To the best of our knowledge, there is no previous work on using muons to measure photo-excited states in organic semiconductors or related materials. Our photo-excitation ideas... -
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... -
characterisation of muonium in functionalized acenes
We wish to measure the high field ALCs of a series of related functionalised acenes, to understand the role of the ligands on the electron spin relaxation, which is of... -
High Temperature μSR Study of Green Dioptase: Muon or Proton Diffusion?
Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D... -
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.... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Ultrafast motion of molecular rotors in metal-organic frameworks: a muon-spin...
In recent years, amphidynamic crystals have gained more and more attention as a state of matter somehow intermediate between solids and liquids. In fact, although these systems... -
Spin fluctuations in heavy fermion system
A study of the ground state of the Ce5Rh4Sn10 is proposed. Compound belongs to the heavy fermion system with two magnetic phase transitions at 1.4 K and 4.3 K. While the... -

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... -
MuSR Study of Magnetically Frustrated Lu2Mo2(O,N)7 pyrochlores
The combination of magnetic frustration and low magnetic moment leads to non-classical magnetic behaviour such as spin liquid states. We have prepared polycrystalline samples of... -
Magnetic ordering and correlation phenomena in the rare-earth RT2Al10 compounds
RT2Al10 is a new series of rare-earth-based ternary aluminide compounds that show a variety of magnetic phenomena. This proposal is for a muSR study on three of its members to... -
Magnetic Ground State of a New Honeycomb Iridate
A new layered iridate material, Cu2IrO3, has been fabricated. This material is isostructural with the much-studied Na2IrO3 and has a nearly ideal honeycomb structure that should... -
Muonium in BeO
BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
Investigation of short range magnetic correlations in CeIr3Si2 using SR
CeIr3Si2 reveals highly anisotropic bulk properties with two magnetic transitions at TN1 ~ 3.9 K and TN2 ~ 3.1 K. The overall crystal electric field (CEF) splitting of the J=5/2... -
