Recently, our group has prepared a series of new double perovskite materials (Li1.5La1.5MO6, M=W6+, Te6+) which display interesting electrochemical behaviour for use in Li-ion... -
A search for transverse phonons in DNA
We have begun an experimental program to investigate the denaturing of DNA, using scattering techniques, to test statistical mechanical models for the moelcule. It is believed... -
Impact of Jahn-Teller Distortions in Sr0.5Pr0.5MnO3
We propose to use the HRPD to establish the sequence of structures, and the nature of the transitions between these, in two complex manganites Sr0.5Pr0.5MnO3 and... -
Low temperature phase transitions in ferroelectric tris-sarcosine calcium chl...
Small-molecule based ferroelectrics offer several advantages over the currently used materials based on heavy metal oxides (i.e. cost, environmental-friendliness). There are... -
Neutron Diffraction Study of a Spin-1/2 Pyrochlore Lu2Mo2O5N2
Ammonolysis of R2Mo2O7 pyrochlores gives R2Mo2O5N2 containing S = ½ Mo5+. They are excellent candidate materials for investigation of quantum spin liquid phenomena and we have... -

The multiferroic perovskite BiFeO3 is the only material that displays both ferroelectric and antiferromagnetic order at RT. Significant efforts are aimed at better understanding... -
Local structure of bulk and nanocrystalline Chromium
We plan to study the coupling between magnetic properties and local structure of polycrystalline and nanocrystalline chromium. Chromium undergoes a magnetic ordering transition... -
Structural Studies of PbZr1-xTixO3: completing the puzzle in the tetragonal a...
We request 6 days of HRPD time in order to study the structures on the tetragonal side of the lead zirconate-titanate (PZT) phase diagram, a region that has so far been rather... -
Search for magnetic order in the coupled S=1/2 two-leg spin ladder system Ba2...
Ba2CuTeO6 is a newly discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that this material is in very close proximity to the quantum critical... -
Structural basis for the 2D thermal expansion tensor of petalite, LiAlSi4O10
Phases in the lithia-alumina-silica phase diagram (LAS) are of great importance owing to the technologically property of ultra-low thermal expansion (ULTE) that they frequently... -
The structure of metal-ammonia Ogg glasses
In this application we will conduct the first detailed study of the structure of glassy metal-ammonia systems ? so-called Ogg glasses, named after the person who first proposed... -

The magnetic excitations will be studied in a powdered sample of 3% CoO in 97% MgO in order to to study the excitations of isolated Co ions and of isolated pairs of Co ions.... -
Investigation of interface magnetism in LSMO/LNO heterostructures
The exchange bias effect (EBE) initially observed at ferromagnetic (FM)/antiferromagnetic (AFM) interfaces in correlated rare earth oxides has been a topic of intense research... -
Magnetostriction in (Bi,La) orthoferrites
We have recently observed unusual magnetostrictive behaviour in Bi0.5La0.5FeO3 (BLFO), a phenomenon which is not present in either solid solution end member. This proposal seeks... -
The coupling of spin and charge correlations in La2-xSrxCuO4
Charge density wave (CDW) order has recently been established as a generic feature of high-temperature cuprate superconductors. It occurs near 1/8 doping and has been observed... -
Crystal Field Excitations in the Borderline Spin Ice Pr2Zr2O7
The title compound is expected to be a spin ice close to an instability which stabilises magnetic order. We can determine its spin Hamiltonian precisely by measuring the crystal... -
Low-temperature Neutron diffraction studies in SrTi0.5Mn0.5O3 to explain the ...
Geometric frustration of magnetic ordering in ordered double perovskites (ODPs) leads to spin-glass, spin-liquid and spin-ice states. However it is yet not clear whether these... -
Investigating Modulation in Molecular Materials:
Valuable information is lost when the focus is put only on the average unit cell and not the long-range order of the whole crystal. Determination of the long-range ordering can...
