We intend to detail the muonium dynamics and investigate the interaction with charge carriers in n-type ZnSe. A doped ZnSe sample (resistivity=10^4 Ohm.cm, n=10^13 cm^-3) is...

Perovskite solar cells (PSCs) are a new generation of solar technology which has shown huge promise with regards to performance, but still suffers from several flaws preventing...

Cubic A2B2O7 oxides with A standing for a rare-earth element and B for a transition or main block metal have been systematically studied for their frequently exotic...

Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns...

The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism...

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...

The research on energy storage devices such as lithium-ion batteries (LIBs) is vital for electric vehicles (EVs), electronic devices and grid-scale energy storage. According to...

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)...

Recently, it has been reported that CeFeAsO belongs to orthorhombic structure where both Fe and Ce moments order antiferromagnetically around 140K and 4K, respectively, whereas...

Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen content. Most...

Our report of a novel cationic dipalladium(I) hydride in (Angew. Chem. Int. Ed. 2010, 49, 6315) shows a linear Pd-Pd-H core with H-ligand dynamics (solution NMR). Ab-initio MD...

Recently the 5d transition metal oxide Sr2IrO4 has attracted much attention due to its close analogy with high-Tc cuprates. A hidden broken symmetry phase, which is similar to...

As a consequence of cation disorder, the compound La3Ni2SbO9 behaves as a new type of magnetic material, a "relaxor ferromagnet", somewhat analogous to a relaxor ferroelectric,...

We propose to study the evolution of ZF-muSR and low-field (100 G) TF-muSR spectra and relaxation times across the charge ordering temperature T0 = 140 K of RbFe2As2 iron based...

We have recently performed muon measurements on a member of a new class of multiferroic materials. We have shown that there is hysteretic behaviour to the internal field...

Materials exhibiting giant magnetocaloric effect (i.e. the large temperature change under a magnetic field variation) are the most promising type for magnetic refrigeration....

One-dimensional (1D) spin chain is important for understanding low-dimensional magnetism and useful for advancing quantum communications. In the present proposal we are...

This proposal describes a muSR experiment on Li-deficient Lix(Ni1/3Co1/3Mn1/3)O2 to determine a Li diffusion coefficient as a function of the Li content x, because muSR is a...

The overall aims of our project is to advance the performance of NIBs in terms of energy and power density by creating a closed-loop approach for materials design,...

Our recent experiment showed that muons implanted into black phosphorus (the most stable allotrope of the element, with a low band gap of 0.3eV) are apparently diamagnetic, with...
