Spin excitations in CeCoSi under hydrostatic pressure
The meta-orbital transition is a new theoretical concept to explain the nature of quantum criticality in heavy-fermion systems. Such a transition can occur e.g. as function of... -
Determination of the relative magnitudes of static and dynamic displacements ...
The width of a peak in a pair distribution function (PDF) provides a measure of the variation in the distance between a pair of atoms. This results from a combination of thermal... -
Magnetostructural study of Percolation Behaviour in Double Perovskites Ba2Fe1...
We propose to use two days of beamtime on POLARIS to determine the structure and magnetic ordering that occurs in a series of cation-ordered perovskites. These cubic compounds... -
Investigation of new fluorinated and reductively defluorinated phases with Ru...
Fluoride Ion Batteries (FIB) are alternative energy storage systems which work based on the transport of fluoride ions between the electrochemically active electrode materials.... -
Negative thermal expansion in ReO3: anomalous variation with temperature
ReO3 is a well-known oxide framework with unusual thermal expansion behaviour, exhibiting multiple regions of both positive and negative thermal expansion (NTE). We propose to... -
Continuation: 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... -
Violation of y-scaling in D2 ¿ Test of existing theories
The applicants aim to perform the most authoritative measurements of NCS profiles by controlling and precisely quantifying everything to do with the sample. In July 2008 we... -
Role of electronic nematicity in the complex magnetism of heavy fermion CeAuS...
CeAuSb2 is a rare earth intermetallic with mesoscale spin-density wave (SDW) magnetic order below 6.6 K. Starting from a simple single-q SDW phase, application of a magnetic... -
Temperature dependence of the diffuse magnetic scattering in CsNiCl3: SXD dat...
The compound CsNiCl3 crystallises in a hexagonal structure and is comprised of chains of NiCl6 octahedra along the c-axis and Cs in-between acting as a spacer to separate the... -
Exploration of the pressure-induced amorphization and glassy states of THF-cl...
Clathrate hydrates (CHs) are ice structures in which water molecules (host) form cages through hydrogen bonds. The cages can accommodate various types of molecules (guests),... -
Search for the magnetic photon in a candidate quantum spin ice
Recent theoretical analyses of quantum spin ice has revealed the present of a novel magnetic excitation whose quantum properties are analogous to photons. This mode is a... -
Local origin of the fluctuating groundstate in an S=1/2 spinel
Upon cooling, all common liquids are observed to freeze. This observation is similarly ubiquitous for magnetic materials, where the magnetic moments most often line up in a... -
High temperature superstructures in thermoelectric oxides
Sodium cobalate has emerged as one of the best thermoelectric materials. Our previous neutron Laue diffraction studies on SXD have found ordered arrays of multivacancy clusters,... -
Determination of the Magnetic Properties of LaFeAs1-xPxO Across Multiple Magn...
LaFeAs1-xPxO has recently been proposed to display unusual properties as a function of P doping with two distinct superconducting (SC) domes separated by a possible AFM phase as... -
Vibrational property analysis of NH4BH4 using inelastic neutron scattering
The proposed experiment at ISIS aims at the characterization of the vibrational properties of ammonium borohydride, NH4BH4, which possess the highest gravimetric H density (~25... -
Pressure-induced O(2) quantum phase transition in a quantum antiferromagnet
Quantum phase transitions (QPT) continue to attract the attention of experimentalists and theorists alike. Experiments on quantum magnets have been crucial to understand their... -
The microscopic structure of the acetone - chloroform azeotrope
The acetone - chloroform system is the classic textbook example of a negative-pressure azeotrope, i.e. the vapour pressures of the binary mixtures are lower than expected for... -
Single-Crystal Neutron Diffraction Study on [U(C5Me5)2(H)(mu¿H)]2
To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently... -
Local structure of the ferroelectric and giant barocaloric (ND4)2SO4
Ammonium sulfate has a well-known order-disorder phase transition at -50 ºC: initially of interest for the ferroelectric behaviour in the low-temperature phase, this has... -
