We propose zero-field depolarization measurements to investigate the motional dynamics of diamagnetic muonium centers in hafnium oxide (HfO2), tungsten oxide (WO3) and zirconium...

A continued study of muonium diffusion in transparent conducting oxides (TCO) are proposed. We have ZF depolarization measurements conducted up to room temperatures for SnO2 and...

This experiment is focused on exploring and harnessing magnetic ground state of the multiferroic materials, with particular emphasis on the hexagonal (h), rare-earth ferrites...

This is a continuation proposal describing an "in situ" muSR experiment on hydrogen storage materials. For the two previous beam-time allocated for RB1510262 and RB1520259, we...

This proposal describes a muSR experiment for studying a diffusive nature of Li ions in novel anode material for Li-ion batteries. The target compound, LixY2Ti2O5S2 (LxYTOS,...

Multiferroic systems have been a long-lasting and productive research field of condensed matter physics in both fundamental and applied perspectives. Useful multiferroic systems...

Lithium (Li) ion batteries is the most common battery technology but lately also sodium (Na) batteries are being considered. One reason is that the Li-reserves are limited and...

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...

We ask for 3 days on EMU to study the Muon spectroscopy of both LiBH4 and Ca(BH4)2 as a function of temperature from 90K-650K. These materials have been extensively...

Amorphous molecular magnetic materials Ni2(OA) (OA:organic acceptor) were reported to exhibit ferromagnetism with Curie temperatures >400K. This work is controversial as it...

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...

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...

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...

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...

When we know an intrinsic diffusion coefficient of Li-ion (D) in an ionic conductor, we could estimate a number of mobile Li ions, i.e. carrier density (n), from ionic...

Experiment is proposed to identify magnetic polaron bound to the muon using RF-muSR. In recent experiment at TRIUMF magnetic polaron was found in transverse field and its...

We propose to obtain the detailed temperature dependent diffusion characteristics for diamagnetic muonium defect centres, assumed to be a 'bare' muon, in selected members of the...

This experiment aims at studying the magnetic behaviour of the molecular square complex {[Fe{B(pz)_4}(CN)_3]_2[Co(bik)_2]_2}(ClO_4)_2 . 3H_2O [B(pz)_4 = tetrapyrazolylborate,...

Lithium-excess cathode materials can deliver high capacity and lead to high energy density. Lithium-excess cathode materials are categorized as “ordered” and “disordered” on the...

With increasing demands for high performance/capacity rechargeable batteries the materials science community is currently facing two severe issues. First of all there is from a...
