Magnetic Properties of Rare-Earth Carbonates
We have prepared a new family of rare-earth carbonates, R4(CO3)6(H2O)2en (R=Dy-Lu). With the exception of R=Er, all materials exhibit a steadily decreasing meff below 70K. The... -
Search for Antiferromagnetic order in ZrMn2
Today, about seventy years after Laves, there exists a fairly good knowledge about the basic structural principles of Laves phases but many questions still remain. AMn-type... -
Investigation of the low temperature, applied field magnetic order in copper-...
We propose to fully explore the field induced magnetically ordered phase of copper-nitrate, Cu(NO3)2.2.5D2O, at temperatures below 0.13 K and in fields up to 5 T. The key aims... -
Critical scattering and coupled order parameters in the ferromagnetic superco...
We propose to conduct a high resolution neutron inelastic scattering study of the ferromagnetic superconductor UCoGe. Initial polarised results obtained at 4F1 (Saclay) are... -
Copy of: Local magnetic order and the paramagnetic-parmagnetic transition in MnO
The antiferromagnetic-paramagnetic transition in MnO at 118 K occurs at a much lower temperature than anticipated from its Curie-Weiss constant theta~550 K. Consequently, strong... -
Na order and diffusion in NaxCoO2: Part II
Recently there have been reports that high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at low... -
Time reversal symmetry breaking in superconducting PrOs4Sb12 and its alloys
In 2005 we carried out muon spin relaxation (muSR) experiments in Pr(Os1-xRux)4Sb12 alloys at KEK, Tsukuba, Japan, to investigate the time-reversal symmetry breaking found in... -
The XY pyrochlore AFM:spin dynamics upon rare-earth dilution in Er2Ti2O7 (CON...
Er2Ti2O7 constitutes an experimental realization of the <111> easy-plane pyrochlore AFM and orders at 1.1 K into the theoretically predicted spin structure. However, the... -
The intermediate stages of hydrogen disorder to order phase transitions in ice
In recent years, our team has discovered three new phases of ice: ices XIII, XIV and XV. On the basis of calorimetric data and some limited diffraction data collected on GEM we... -

Structure and magnetic order in chemically modified schafarzikites
Schafarzikite minerals are structurally interesting in having 1-D chains of edge-linked transition metal octahedra. This experiment aims to determine the cause of the... -
Muonium Defect Levels in 4H Silicon Carbide
We propose to obtain the temperature dependence of the diamagnetic spin-precession amplitudes up to 1100 K for the three electrical types of 4H-SiC in order to extract the Mu... -
Anion order in perovskite oxynitrides
Transition metal oxynitrides with perovskite type structures are an emerging class of materials with optical, photocatalytic, dielectric and magnetoresistive properties that may... -
Magnetic order in weakly coupled molecular magnetic systems
Two molecular magnetic systems are considered which show low-temperature ordered states. One of them is F4BImNN, a nitronyl nitroxide radical magnet, an excellent realization of... -
Magnetic excitations in mesoporous hematite
We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One... -
Na order and diffusion in NaxCoO2: a route to tuning of thermoelectric & magn...
Recently there have been many reports on how high-temperature sodium order and dynamics in NaxCoO2 (NCO) can strongly influence both the electronic & magnetic properties at... -
Spin and cation order in AMn3B4O12 perovskites
A-site-ordered perovskite oxides with formula AA'3B4O12 have a rich variety of physical and chemical properties. Most have Jahn-Teller active Cu2+ or Mn3+ at the square-planar... -
Investigating the structural features and magnetic order in novel perovskite ...
Through low temperature fluorination of AFeO3-x (A=Sr, Ba) it is possible to prepare the oxide fluorides AFeO2F, which are antiferromagnetically ordered at room temperature. In... -
Study of the bioprotective effectiveness of trehalose/glycerol mixtures on ly...
The proposed experiment aims to study the dynamics of hydrated lysozyme in presence of trehalose, glycerol and trehalose/glycerol mixtures at different relative concentration in... -
Magnetic order in Mott insulating kappa-(BEDT-TTF)2Cu[N(CN)2]Cl
The quasi-two-dimensional molecular series kappa-(BEDT-TTF)2X exemplifies the complex interplay of collective phenomena that occur in correlated electron systems. Many of the...
