Iron-based superconductors with molecular spacer layers: probing Li diffusion...
All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make... -
Spin dynamics of the Heisenberg triangular antiferromagnet KCrO2
The members of the series ACrO2 (where A=Li, Na, K) comprise well-decoupled, highly ideal triangular planes containing isotropic spins. While the A=Li and Na materials have been... -
Investigating Magnetic Ordering in Ba2MnWO6 and Sr2MnWO6
Cubic double perovskites provide a rare example of an undistorted face-centred cubic lattice, made up of edge sharing regular tetrahedra. In Ba2MnWO6, antiferromagnetically... -
Influence of the cation disorder on the magnetic properties of underdoped cup...
We want to isolate the effects of doping, charge localization and local distortion on the transition from insulating antiferromagnet to superconducting metal in YBCO. We choose... -
μSR investigations of multiferroic system RCrTiO5 (R= rare-earth)
We are currently investigating multiferroic system RCrTiO5 (R= rare-earth) using bulk measurements and have found interesting magnetic properties. To understand the nature of... -
MuSR studies of the electronic properties of hyperexpanded fullerides close t...
The fcc polymorph of the hyperexpanded fulleride Cs3C60 can be driven to a bulk suprconducting state without symmetry change by the application of pressure. Its Tc passes... -
muSR studies of AF/SC/normal phase interplays in La2-xSrxCuO4 and Ba(Fe,Ni)2As2
We propose muSR studies on superfluid density in the overdoped La2-xSrxCuO4 (LSCO). The Hayden group (Bristol) has been growing high-quality LSCO single crystals, and performed... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Muon spin rotation study on PrTSi3 (T = Ir, Rh and Ru)
Recently we have investigated three new ternary intermetallic compounds PrTSi3 (T = Ir, Rh and Ru) which form in BaNiSn3-type tetragonal structure. The susceptibility exhibits... -
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... -
Rapid Access: Determination of the Magnetic Properties of LaFeAs1-xPxO Across...
Using NMR spectroscopy, the possible existence of a new magnetic state has been suggested to exist in LaFeAs1-xPxO (for x near 0.5); however, other groups failed to detect any... -
Studying the metamagnetism of FeCl2 and FeBr2 using HiFi
Work on the iron halides FeX2 has led to the models of A-type antiferromagnetism and the tricritical point in magnetic systems. Here we wish to carry out decoupling experiments... -

Muon-spin rotation study of the in-plane magnetic penetration depth of REFe_(...
We propose a TF-muSR investigation of the superconducting properties of the REFe_(1-y)Ru_yAsO_{1-x}F_x compound (RE=La, Sm). In this system the substitution of Fe by the... -
Soft chemistry tuning between magnetism and superconductivity in K{1-x}Fe{2-y...
Traditional high-temperature synthesis techniques can be used to vary the composition of K{1-x}Fe{2-y}Se2 up to certain limits. We have found a way to extend the limits on the K... -
Spin anisotropy of Seff=1/2 triangular rare-earth based antiferromagnets
In quantum magnetism significant efforts have been devoted to the search for new quantum states. In particular the Quantum Spin Liquid (QSL) state on the triangular lattice has... -
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... -
RF MuSR in the gas phase: The Search for a Radical State (RB920227)
The main spectroscopic technique for studying radicals in solids and liquids, ESR, cannot usually be used to study radicals of more than 3-5 atoms in the gas phase due to strong... -
Local Field fluctuations and Mu Dynamics in Vanadium Dioxide Compounds
This is an in depth study of magnetic fluctuations and local field dynamics leading into the low temperature magnetic phase of Vanadium Oxide compounds (VO2, VO2:W and VO2:Ti)... -
