We propose a TF-muSR investigation of the superconducting properties of the REFe_(1-y)Ru_yAsO_{1-x}F_x compound (RE=La, Sm). In this system the substitution of Fe by the... -
Investigating the muon radical in Sulphur
Recent muon level-crossing measurements in the stable orthorhombic alpha-phase of sulphur indicate the existence of a radical state, with an interesting temperature evolution.... -
Muon spin relaxation studies of KTCNQ and related compounds
Potassium tetracyanoquinodimenthane (KTCNQ) undergoes a spin-Peierls (SP) transition at 396K where a transformation from uniform to dimerised TCNQ- molecules in 1D columns... -
Probing Li+ diffusion mechanics in NCA nano and bulk materials
Recent advances in energy materials have led to the development of high capacity insertion cathodes for Li-ion batteries. A relatively new, yet attractive material is nickel... -

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... -
In-operando diffusion measurements on an all-solid-state battery cell
We propose to use muons to probe the diffusion processes which occur within a battery anode during cycling in an all solid-state battery. Such solid-state battery configurations... -

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... -
MuSR study on the hidden order in Irridates
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... -
muSR study of a relaxor ferromagnet
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,... -
