This proposal is part of our research programme on spin and orbital order in frustrated systems. AgNiO2 has a layered crystal structure with Jahn-Teller active Ni3+ ions forming...

We plan to investigate by means of longitudinal and zero field muSR the modifications induced by (Zn,Mg) for Cu substitution in the spin correlations of Sr2CuO2Cl2, a...

The goal of this proposal is to measure and characterize the Single Event Effects (SEEs) produced by neutrons available at ISIS in different commercial and state-of-the-art...

In recent years, nanoparticles have been a major source of interest in a wide range of fields. Our long term objectives are tuning the free radical reactivity on the surface of...

Crystals of the filled skutterudite PrFe4Sb12 with the 73~87% Pr-site filling fractions prepared under ambient pressure show some magnetic ordering around 5 K and their...

The properties of pnictide superconductors can be controlled exquisitely by chemical doping. We have identified some key systems in which to explore this effect which should...

In recent years, the noble metals nanoparticles (MNPs) have been the subject of intense interest in areas of materials science, biotechnology, medicine and organic chemistry for...

Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the...

The effect of order-disorder transitions on the conductivity of oxide ion conducting electrolytes has attracted significant attention in the literature. In contrast there has...

Multiferroics are promising candidates for faster and cooler electronics. Due to the intrinsic incompatibility between the ferromagnetic (FM) and ferroelectric (FE) phases, it...

Oxide ceramics based on ceria, CeO2, have been the subject of considerable research for the role of solid electrolyte within solid oxide fuel cells (SOFCs), since their ionic...

Oxides of 5d elements such as Ir and Os have been attracting much attention as candidates to realize novel types of electronic ground states stabilized by the strong spin orbit...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

Our previous LF-µSR measurements in natural type Ia single crystal diamond showed some evidence of the ionization of bond-centred muonium (MuBC) from around 1000K. This was...

Using conjugated polymers as the active materials in electronic and optoelectronic devices opens up the possibility of fabricating all-polymer devices, such as active matrix...

The concept of an electronic nematic, in which the electronic wavefunctions have different symmetry to the crystal structure, has been proposed to explain several unusual...

We have been recently successful in isolating the fcc polymorph of the key hyperexpandedfulleride Cs3C60 - this phase can be driven from an insulating to a bulk suprconducting...

We propose to investigate the spin dynamics in the Ortho-II order YBCO6.5 superconductor at energies above 100 meV. This study will be aimed at searching for the broadening of...

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...

Many room temperature ionic liquids (salts with melting points near room temperature that hereafter will be referred to as ionic liquids) are ¿green solvents¿ for chemical...
