Investigation of the magnetic phases of the charge transfer compound CuTCNQ
The charge transfer compound CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) exhibits switching between two electrical resistance states when subject to an electric field. It... -
The magnetic excitation spectrum in Fe1.07Te
We propose to investigate the high energy magnetic spectrum in Fe1.07Te. We have previously investigated the fluctuations in Fe1.14Te in the incommensurate phase and have found... -
ALCs investigation of the polymer PTAA (chain length = 80)
This proposal aims to study the avoided level crossing resonances (ALCs) of the amorphous polymer PTAA, with chain length 80. Previous measurements on PTAA have studied a... -
Investigation of Jahn-Teller assisted polaron collapse beyond the percolation...
Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of... -
In search for a new correlated quantum phase in the CDW 1T-TaS2
TaS2 is a quasi-2D metallic compound revealing strong electron-phonon coupling responsible for charge-density-wave (CDW) instabilities. The compound undergoes 3 CDW transitions;... -
Surveying Hebel-Slichter peaks in conventional-ish superconductors
The presence of a Hebel-Slichter peak in NMR or µSR measurements just below the critical temperature of superconductors is taken to be strong evidence for conventional behaviour... -
Onset of classical dynamics in ammonium hexachlorometallates.
The piloting experiment (RB 820239) on VESUVIO on (NH4)2PdCl6, has shown that, at 5 and 80K, H momentum distribution, J(y), in NH4+ is non-Gaussian with non-vanishing... -
Muonium Charge-State Transition Energies in Si-Ge Alloys
We propose longitudinal muon spin depolarization measurements for two additional samples of Si(1-x)Ge(x) alloys in order to complete our study of the dependence of Mu(-/0)... -
Frustration-stabilised high-field skyrmions
Magnetic skyrmions are nanometric topological vortex-like spin textures that appear in select materials and have lately attracted a lot of attention due to their numerous... -
Spin liquid properties of the S=1/2 triangular lattice system Li2ZnMo3O8
Thermal, magnetic, neutron and muSR measurements all point towards a gapless or almost gapless spin liquid ground state for the triangular lattice spin system of S=1/2 Mo3... -
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)... -
Is Ba2PrMoO6 a valence bond glass? A MuSR spectroscopic study
It has recently been proposed that Ba2YMoO6 is the first example of an exotic valence bond glass (VBG), which is characterized by an amorphous arrangement of spin dimers and... -
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... -
Exchange interactions and spin gap in Cu2PO4OH
The mineral Libethenite, Cu2PO4OH, is an ideal system in which to study low dimensional quantum magnetism. Its magnetic behaviour is complex but is related to systems with... -
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... -
Discovery of slow magnetic fluctuations in the nematic phase of FeSe1-xSx
In most unconventional superconductors, the importance of antiferromagnetic fluctuations is widely acknowledged. In addition, cuprate and iron-pnictide superconductors often... -
Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 p...
It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually... -
Microscopic characterization of Ba5AlIr2O11
Iridium-containing oxide magnets are interesting because the different interactions controlling their magnetic properties have similar energies associated with them. This leads... -
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... -
µSR investigation of NaxLi12-xC60
An economy based on hydrogen as an energy carrier is one of the most promising solutions against the greenhouse effect problem, due to the large amount of energy produced by the...
