Probing the carrier-induced donor-to-acceptor transition of muonium in indium...
The first experiment we propose is a search for a shallow-donor signal for muonium in indium oxide. Its observation would test our assertion, based on our measurements of... -
Spin dynamics in the ground state of the multiferroic FeTe2O5Br and FeTe2O5Cl
Recently, we have found a new multiferroics material FeTe2O5Br, with simultaneous ferroelectric and incommensurate magnetic orderings appear at TN = 11 K. Our neutron... -
Phonon dynamics in liquid gallium
We propose to measure the inelastic scattering S(Q,E) maps from gallium in its liquid phases across a wide range of temperatures. This proposal is based on a new prediction for... -
A µSR study of single crystals of the superconductor FeSe1 xTex (0≤x...
Superconductivity was recently discovered in alpha-phase FeSex with a Tc of 8 K. Selenium can be replaced with Tellurium (FeSe1-xTex) and this results in an increase in Tc to 15... -
Competing degenrate magnetic states in Ba1-xNaxFe2As2
Magnetic and superconducting ground states have been proposed to coexist in a relatively narrow compositional range in the so-called 122 pnictide superconductors. We recently... -
A muSR spectroscopic study of the spin dynamics and reentrant spin-glass tran...
We have recently synthesised the novel iridocuprate IrSr2Sm1.15Ce0.85Cu2O10. This material exhibits a complex temperature dependence of the magnetic susceptibility with multiple... -
Systematic Investigation of Magnetically Doped Toplogical Insulators
Topological insulators (TIs) are of inherent interest as they are conducting on the surface whilst insulating on the bulk. We would like to investigate magnetically doped... -

muSR in Rare-earth doped Phenanthrene Superconductors
We plan to perform transverse field and zero-field μSR experiments to investigate the temperature dependence of the relaxation rate in the superconducting phase of... -
Varying oxygen content in the quantum spin ice Tb2Ti2O7
Tb2Ti2O7 is one of two compounds identified as potential quantum spin ices. As with other oxide pyrochlores the properties depend sensitively on the oxygen stoichiometry. Most... -
Investigation of the magnetic phase of the charge transfer compound CuTCNQ
CuTCNQ (TCNQ = 7,7,8,8-Tetracyanoquinodimethane) is material which exhibits electrical resistive switching at 300K and has two structural forms (I and II), each with very... -
A Three-dimensional Jahn-Teller distorted Metal-Oxalato-Framework
Muon spin relaxation will be used to study the low temperature magnetic properties of a new metal-oxalato-framework compound [(C2H5)3NH]2Cu2(C2O4)3. This has a three-dimensional... -
Doping effects in a S = 1/2 spin ladder system near quantum criticality
Spin ladders are excellent model systems for studying quantum phase transitions, as they exhibit a quantum critical point between non-magnetic spin singlet dimers to Néel... -
Studying the Temperature Dependence of The Slower μSR Frequencies in CsN...
We seek to continue our study of CsNiCl3 to determine the nature of the two magnetic transitions.Previous experiments at PSI have shown there are two distinct muons sites, one... -
Investigating spin dynamics in spinel spin ice with musr and high freqeuncy s...
Spin ice materials exhibit novel magnetic behaviour because of their atomic interactions and geometric constraints of the crystal lattice. This novel behaviour takes the form of... -
Investigation of antiferromagnetic long-range interactions in Co-based Heusle...
Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of... -
Spin dynamics of Ce in the Noncentrosymmetric Heavy-Fermion Superconductors C...
In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have... -
Study of Magnetic Features in WQeakly Mn-Doped ZnGeP2
Continued investigation of magnetic fluctuations in the Mn-doiped chalcopyrite semiconductor ZnGeP2 is proposed using LF-MuSR depolarization rates. Due to ferromagnetism above... -
Muonium in widegap oxides
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... -
