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)... -
Charting the increase in spin fluctuations as we approach the critical point ...
The LaFe13-xSix system (x<1.6) has a first order ferromagnetic, FM, to paramagnetic, PM, transition that is tunable in magnetic field, ending at a (tri)critical point (Hcrit,... -
High Temperature μSR Study of Green Dioptase: Muon or Proton Diffusion?
Green dioptase is a naturally occurring mineral, that has a deep green colour, similar to that of an emerald, and with a chemical formula of CuSiO3.H2O. The Cu lies in quasi-1D... -
A Self-consistent Description of the Thermoelastic Properties of Dielectric P...
20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid.... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Fluctuating stripes in an insulating hole-doped antiferromagnet
In a recent letter to Nature, Boothroyd and coworkers have shown that the well known hour-glass spectrum, previously observed in some cuprate materials, occurs in a hole doped... -
Muon-spin rotation study of the in-plane magnetic penetration depth of REFe_(...
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... -
Investigation of two frustrated quantum magnets with a novel interaction scheme
The isostructural compounds ACuTe2O6 (A=Sr, Pb) consist of a 3-dimensional arrangement of spin-1/2 Cu ions. There are 3 potentially strong interactions, the first neighbor... -
Muon Studies of Ion Diffusion in Single-Crystal Photovoltaic Materials
In recent years, the family of lead halide perovskite materials (e.g. MAPbI3) has attracted substantial interest due to their unique combination of properties and potential... -
Local Field fluctuations and Mu Dynamics in Vanadium Dioxide Compounds
This is an in depth study of magnetic fluctuations and local field dynamics leading into the low temperature magnetic phase of Vanadium Oxide compounds (VO2, VO2:W and VO2:Ti)... -
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,... -
MuSR Studies of the Proton Conducting Polymer Nafion
The fluorinated ionomer Nafion is a material that provides efficient proton conducting membranes for application in important technological areas such as hydrogen fuel cells.... -
muSR of Polyethylene Oxide: A Simple Proton-Conducting Polymer
Proton-conducting polymer membranes have significant technological applications in hydrogen or methanol fuel cells. muSR can shed light on the mechanisms for proton transport in... -
Molecular Dynamics in Polystyrene
The goal of this experiment is to better understand the molecular dynamics in polystyrene in order to shed light on the discrepancy between beta-NMR and low-energy muSR... -
The Structure of Ca- and Yb-ammonia Solutions: Polarons, Bipolarons and Elect...
In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD... -
Magnetism in NaTiO2
NaTiO2 has been predicted to have a variety of unusual magnetic states, depending sensitively on the details of the crystal structure and interaction strength between the... -
Study of structural and phase transitions of carbon dioxide confined in the n...
The properties of fluids confined in nanopores differ from the bulk mainly due to the solid-fluid interactions and the finite pore size. Such phenomena are of fundamental... -
Impurity-induced frustration in La2CuO4
We plan to investigate by means of zero-field muSR the doping dependence of the sublatticemagnetization in La2Cu1-xZnxO4 and in La2Cu1-xMgxO4. In both systems Cu2+ S=1/2 spins... -
Muon spin rotation studies in Ni-Mn-Sn based metamagnetic shape memory alloys...
Ni2Mn1+pZ1-p (Z= In, Sn, Sb and < p 1) based ferromagnetic shape memory alloys (FSMAs) with Heusler type structure are fascinating materials as far as the magneto-functional... -
Study of pore-confined CO2 depletion below the bulk triple point
Freezing of fluids confined at the nanoscale is of great importance for the understanding of their behaviour due to the confinement effects arising from the finite pore size and...
