Spin Frustration in Iridate Systems, and the Role of the Spin-Orbit Coupling
We propose to investigate the roles of the spin-orbit interaction and geometrical frustration in stabilising a quantum spin liquid phase (QSL) in some iridate systems. µSR is a... -
Hunting for the low-temperature, low-field magnetization plateau in Tb2Ti2O7
Tb2Ti2O7 is a pyrochlore antiferromagnet that has previously been viewed as a spin liquid. This description fails to describe key features of its physics and more recently the... -
Investigation of superconducting ground state of the first Fe-based silicide ...
HTSC in the iron-based superconductors (Fe-SC) is one of the most active and challenging topics. Very recently some of us (F. Bernardini et al.) have reported SC in novel... -
Muonium in BeO
BeO is a promising material in order to improve HfO2-based MOSFET devices, and a candidate substitute of HfO2 as high-k gate material. The electrical properties of BeO can be... -
How complex is complex: an ALC study of a 10-mer helical peptide chain
There have been ALC studies on the interaction of muons with native proteins, but little systematic work that contributes understanding of how spectroscopic information alters... -
muSR studies of expanded fullerides across the superconductivity dome
FCC Cs3C60 can be driven to a bulk superconducting state without symmetry change by the application of pressure. Its Tc passes through a maximum of 35 K at 6 kbar. We have been... -
Understanding the role of spin orbit coupling on superconductivity in ScMX (M...
It is a great interest of research to explore the superconductivity in 111-family superconductor with strong spin orbit-interaction. In this proposal we wish to investigate role... -
Possible muon diffusion in frustrated magnets
Recent investigations into spin ice suggest excitations that behave like magnetic monopoles, this has included a transverse field muon experiment. When zero field muon... -
muSR study of magnetic correlations and their transformation in nanoclusters ...
Only few studies have explored the magnetic correlations in nanocomposites of Cobalt carbide systems. Our magnetization and transport studies on nanocomposites of admixed phases... -
Interaction of muonium centres and excess carriers in highly injected silicon
We have developed a method to measure carrier recombination lifetime in crystalline silicon with the photo-muSR technique. The key of the method is to measure the dependence of... -
The nature of excitations in a molecular Haldane system
It is well known that an S = 1 antiferromagnetic spin chain is predicted to have a quantum disordered ground state and a gap in its excitation spectrum. This so-called Haldane... -
MuSR studies of the magnetic properties of hyperexpanded fullerides close to ...
We have been recently successful in isolating the fcc polymorph of the key hyperexpanded fulleride Cs3C60 - this phase can be driven to a bulk suprconducting state without... -
Investigation of magnetic defects in exfoliated graphite
Graphene has recently received widespread attention, after the discovery of its stability as a 2Dcrystal at ambient conditions and thanks to a wealth of possible applications.... -

Non-collinear Order and Spin Fluctuations in Chiral Cyanide-bridged Molecular...
A series of cyanide-bridged molecular magnets incorporating chiral ligands will be invstigated using muon spin relaxation. The magnets combine Ni(II) with M(III) (M=Fe,Cr,Co).... -
muSR study of a pi-electron S = ½ candidate quantum spin-liquid state in an i...
Molecular solids whose cooperative electronic properties are based purely on pi-electrons from carbon atoms offer a fertile ground in the search for exotic states of matter,... -
Temperature and environment dependence of the isotope effect in muonated radi...
We plan to measure the hyperfine constants for both the muon and the equivalent hydrogen atom in a small muonated radical using time-differential ALC. We will follow this as a... -
Magnetic ordering in AgFBF4 a nearly perfect 1D AFM with huge intra-chain c...
We propose to investigate AgFBF4, a compound known for > 20 years, with muon spectroscopy. The scope is to determine the 3D ordering temperature as well as estimate the value... -
Probing the Magnetism and Suspected Quantum Fluctuations in Green Dioptase
It has been suggested that within green dipotase there the magnetism is dominated by quantum flucuations but evidence for this is not definitive. This means that in this... -
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...
