We propose to develop and carry out a novel in situ SR/electrochemical technique to identify the mechanism underlying ferromagnetism in palladium bionanoparticles. We... -
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... -
Frustration, quantum spin ices and quantum diffusion
This proposal aims to characterise the spin dynamics of three Pr-based pyrochlores that may be realisations of quantum spin ice materials. The lower moment and larger wave... -
DYNAMICS OF SURFACTANTS IN LUBRICATING OILS
In a recent series of successful experiments at PSI and ISIS we were able to demonstrate the possibility of measuring the rate of transfer of a small molecule (allyl alcohol)... -
Spin relaxation of short-lived spin-labelled radicals in solution
The spin relaxation rates of free radicals in solution can provide valuable information about the dynamics of molecular tumbling in solution, and solvent-radical interactions.... -
