RF decoupling of the F-mu-F state
NMR has become an extremely sophisticated experimental technique because of the use of pulse sequences which allow the control and manipulation of a nuclear spin system or... -
Characterizing Mu in 6H-SiC with RF-MuSR
We propose a set of RF measurements on Silicon Carbide (polytype 6H) to identify and characterize the muonium species present below room temperature. One of the main goals of... -
Spin excitations in LiFeAs, a stoichiometric ferropnictide superconductor at ...
We propose to measure the powder-averaged spin excitation spectrum of LiFeAs, a new member of the ferropnictide family of superconductors. This compound is special because it is... -
Crystal field excitations to understand anisotropy behavior in new Ce based h...
Recently we have synthesised new caged-type heavy fermion compounds CeT4Al15 (T=Rh and Ir) and investigated using bulk measurements. The low temperature susceptibility, heat... -
Magnetic Transition in Li-MeNH2
Previously we completed an experiment on ARGUS to determine the extent of magnetic transitions in Li(MeNH2)4. This experiment was designed to overcome sample environment... -
Magnetic self-aggregating ionic liquids (MSAILs)
This proposal is to explore aqueous phase structures with a new class of magnetic self-aggregating ionic liquids (MSAILs) (see Figures 2 and 3 below). The dilute micellar... -
Spectroscopy of muon centres in n-type silicon carbide
We propose a series of measurements to complete the previous direct spectroscopic measurements of the Muonium defect energy levels in Silicon Carbide (SiC; RB110134). We will... -
Antibiotic Interactions with models of the Gram negative bacterial outer memb...
Gram-negative bacteria, which cause a variety of diseases including meningitis, plague, sepsis and food poisoning, are becoming increasingly antibiotic resistant. One reason is... -
Thermal expansion of persubstituited aromatics I: benzene.
Benzene is probably the most studied compound in the history of organic chemistry. Whenever a new experimental technique or theoretical method is being developed most of the... -
Magnetic excitation in triangular latticce antiferromagnet alpha-CaCr2O4
The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different... -
RF-muSR in the gas phase: the muoniated ethyl radical
Radio-frequency muon spin resonance is an exceptional technique for studying free radicals, but it has not been applied to study radicals in the gas phase. In a previous... -
Neutron reflectometry study of liquid 3He/4He mixture surface
In our recent experiment RB1120146 we obtained exciting new results on neutron scattering from the liquid helium surface. At 2.3K there was no difference in reflectivity between... -
A Study of AuMu^+ Final States by Dia RF Resonance
Small-sized metal nanoparticles (NPs) are of long standing interest to both magnetism and heterogeneous catalysis. Recent muSR studies of Au NPs encapsulated in mesoporous... -
Magnetic excitations in single-crystals of LaFeAsO
We aim to determine the magnetic excitation spectrum in single-crystals of the parent LaFeAsO compound and thereby address some basic issues concerning the nature of the... -
Spin excitations in the paramagnetic phase of a charge-ordered bilayered mang...
In a previous experiment we measured the spin wave spectrum of the half-doped bilayer manganite Pr(Ca,Sr)2Mn2O7 in its spin, charge and orbital ordered phase. The data, which... -
High-p/T setup and Anvil Material Testing
We request 6 days commissioning time be allocated on PEARL for the on-line testing of new high-p/T furnace setups and new anvil materials. -
High Pressure Thermoelastic Properties of Thermoelectric PbSe
We propose to study the effect of pressure and temperature on the crystal structure and the elasticproperties of lead selenide, an important material for conversion of waste... -
Magnetic Ionic Liquids: measuring the ions diffusion as a function of the ap...
New ionic liquids made of diamagnetic cations and anions consisting of d- and f- transition metal complexes are gaining increasing recognition because of their marked... -
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... -
