Geometrically frustrated antiferromagnets RBa(Co/Fe)4O7 (R=rare earth or Y) exhibit a weak ferromagnetic component in the high-temperature spin-liquid phase. Based on a symmetry...

Previous muon experiments have identified a muonium state in the commonly occuring, but complex, beta rhombohedral form of elemental boron. To complement recent theoretical work...

Mn have been found to be an interesting ion to be used as dopant in Lithium Niobate (LiNbO3) crystals in order to enhance their photorefractive properties. These materials are...

We wish to complete muon spectroscopic experiments on materials from a ceramic system of interest for possible solid electrolyte applications in lithium-ion battery devices:...

LiFePO4 (LFP) is a commercially applied cathode material for lithium ion batteries. With its Li ion hopping predominantly occurring along one-dimensional channels, LFP is a very...

We propose to perform a neutron inelastic scattering study on the anisotropic triangular lattice system beta-NaMnO2. This work will be an extension of our previous study on...

In order to estimate a reliable reaction area (a_r) between cathode and liquid electrolyte in a Li-ion battery, we wish to propose a muSR experiment on a charged-state cathode...

The structure and dynamics of hydrogen (H) defects in tungsten recently become a topic of major interest since this metal has been chosen as shielding material for the next step...

This proposal describes a continuation muSR experiment on Li-Mn-oxides to see Li diffusion, because muSR is a powerful technique to detect it in the compounds containing...

A basic understanding of the dynamic processes in polystyrene (PS) is a question of utmost interest and has technological ramifications due to its importance in commercial...

We found that muSR detects Li-diffusion in LixCoO2, LiNiO2, Lix(NiCoMn)O2 and LiFePO4 through a dynamic behavior of nuclear field relaxation. Very recently, we have also found...

We propose to study the dynamics of the central Fe spin in reduced model Fe-porphyrins. Our aim is to clarify a relatioship between the spin dynamics of Fe and functions of...

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...

In order to improve the performance of future energy devices, nano-structured materials is one of the most promising routes. LiFePO4 is a commercial battery cathode material...

The compounds belonging to the series of TMOs NaM2O4 (M = Ti, V, Mn, Cr) share the same interesting properties: they are all Q1D metallic antiferromagnets with the Na ions...

LiFePO4 is cathode material for Li ion batteries. One of the key functional properties is the Li-ion diffusion. Theoretical calculations showed that Li diffusion along the [010]...

Lead Halide perovskite solar cells are the next generation of solar cells, likely to over take silicon and organic solar cells in applications within the next 5-10 years. Lead...
