A muSR Investigation of the Magnetic Ground State and Spin Dynamics in the Tr...
In a typical magnetic material the interactions between neighbouring magnetic moments will tend to lead to their ordered alignment throughout the entire structure as it is... -
Muon spin relaxation study on cobalt arsenides ACo2As2 (A = Ca, Sr and Ba)
Recent investigations of physical properties of ACo2As2 (A = Ca, Sr, Ba) indicate that Co-based arsenides could be a potential parent compound like the parent AFe2As2. While... -
Muonium Charge-State Transition Energies in Si-Ge Alloys
We propose longitudinal muon spin depolarization measurements for two additional samples of Si(1-x)Ge(x) alloys in order to complete our study of the dependence of Mu(-/0)... -
Muon spin relaxation study of R2RuO5 (R = Pr, Nd, Sm, Tb)
R2RuO5 (R = Pr, Nd, Sm, Gd, Tb) are known to exhibit interesting physical properties. They all show magnetic ordering between 8 ¿ 24 K. They also show large Sommerfeld... -
Spin liquid properties of the S=1/2 triangular lattice system Li2ZnMo3O8
Thermal, magnetic, neutron and muSR measurements all point towards a gapless or almost gapless spin liquid ground state for the triangular lattice spin system of S=1/2 Mo3... -
Studies of Free Radical Final States on Au nanoparticles by RF-muSR and ALC S...
Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent µSR studies of bare Au NPs encapsulated in mesoporous... -

All known iron-based superconductors comprise layers of FeAs or FeSe with some combination of group I, group II or lanthanide oxide layers, and usually some doping. To make... -
Short range magnetic order in the compositionally modulated Bi2Cr4/3Ni2/3O6 p...
It is particularly challenging to synthesize a novel multiferroic material as it seems that the mechanisms that allow ferromagnets and ferroelectrics to work are mutually... -
Coupling of chains in a new, highly tuneable, isostructural series of model q...
Here we propose measurements on a unique, newly synthesized series of coordination polymers based on chains of Cu2+ ions. These have been designed with the intention of... -
