Ground state of the layered triangular antiferromagnet YbZnGaO4
YbMgGaO4 and YbZnGaO4 are recently discovered triangular antiferromagnets , which contain quasi-2D layers of Yb3+ ions. These ions experience strong spin orbit coupling and have... -
µSR study of the magnetic ordering in the S=1 linear chain compound KNiCl3.
We propose to continue our study of KNiCl3, a 1D S=1 linear chain compound. Our previous work has shown evidence for two magnetic transitions between 2 and 15 K. Experiments at... -
Degenerate ground-states in Ho2-xYxSn2O7
Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the... -
In Situ Measurement of the Spin Seebeck Effect
The spin Seebeck effect is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric energy generators. Spin... -
Low Temperature Magnetic Behaviour of Sm2Zr2O7
Pyrochlore oxides of the type A2B2O7 (where A = trivalent rare earth, B = tetravalent transition metal element) can form geometrically frustrated magnets displaying a range of... -
Muon spin relaxation study of biskyrmions in MnNiGa
Skyrmions are chiral spin textures that exist in a variety of magnetic materials. These states are topologically non-trivial, which gives them stability expected to be useful... -
Basic Science for Offpsec : Part 2
This proposal is part 2 of a set of two proposals on Offspec aimed at understanding some of the effects seen in off-specular data and in particular the use of the spin echo... -
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... -
Investigation of the multiferroic materials Ba3Dy2GaNb9O30 and Ba3.5Dy2Ga1.5N...
We have recently performed a ZF muon experiment on Ba3Dy2GaNb9O30 in EMU under the influence of electric fields and demonstrated that this material demonstrates multiferroic... -
The role of spin fluctuations, disorder and non-colinearity in the INVAR effect
The origin of the Invar effect, whereby certain ferromagnetic alloys exhibit near zero thermal expansion around room temperature is still not properly understood. Although the... -
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... -
Musr on a 2D quantum spin liquid candidate material without structural disorder.
The ordered double perovskite Sr2CuWO6 is a quasi-two dimensional J1/J2 frustrated square lattice model antiferromagnet. The divalent Cu carries S = 1/2 while the W (VI) is 4d0.... -
Does ozone initiate damage to the main pulmonary surfactant lipid, DPPC, or c...
Exposure to ozone gas can cause inflammation of the airways and breathing difficulties. The initial reaction of ozone is thought to be predominantly with lipids present in the... -
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... -
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... -
Investigating the effect of magnetic impurities on P3HT ALC resonances.
Previous work on the polymer RR-P3HT has found that the ALC resonance collapses at 100K to ~80% of the 300K ALC magnitude, this is much larger than the decrease seen for small... -
The Impact of Multivalent Counterions on the Surface Adsorption of the Anioni...
Surface multilayer formation provides great potential for the tuning and optimising surface wetting properties and applications such as lubrication, drug delivery. Normally... -
Superconducting intercalates of FeSe tuned in situ with ammonia
We propose to study two phases of Na-NH3 intercalated FeSe which have distinct values of Tc, both close to 40 K, but different concentrations of NH3 and quite distinct crystal... -
Metal decorated graphene for Hydrogen Storage
Previous uSR measurements on chemically produced graphene showed that, apart from a slowly relaxing graphite-like fraction, approximately 40% of the implanted muons are trapped... -
The interaction of Plant Defensins with Model Lipid Membranes : Understanding...
Plants do not have the sophisticated immunoglobulin immune systems of vertibrates, instead they posses a series of stimuli based responses which defend against pathogentic...
