Compressibility and Tilting of Polyhedra within Sr2NiMoO6 at High Pressure
Ordered double perovskites (also known as elpasolites) have the general formula A2BBO6 where A is generally a rare earth metal or alkaline earth metal and where B and B are... -
Structural distortions at low temperature on the pyrochlore Yb2Ti2O7
Magnetic frustration occurs when nearest-neighbor competing interactions cannot be simultaneously satisfied. Pyrochlores, whose crystalline lattices form corner-sharing... -
Thermoelastic properties of ammonium sulfate, (ND4)2SO4, and the P-T dependen...
Ammonium sulfate exhibits a first-order phase transition upon cooling through ~ 224 K at room pressure, from a paraelectric to a ferroelectric crystal. There have been no... -
Muon probes of hydrogen-bond network in supercooled water
Muon diamagnetic fraction in liquid water is known to decrease with decreasing temperature probably because its formation mechanism results from the structural alternation and... -
High pressure effects on Jahn-Teller distortion in metal-formate perovskites
The family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials¿ magnetic and electric properties, in... -
Investigation of the phases formed during the conversion reaction of the C-ba...
FeF2 is a conversion reaction material that undergoes a reaction with lithium: FeF2+2Li++2e-<->2LiF+Fe, which results in a high theoretical capacity, 571 mA/g.... -

RBaCo4O7 (R = rare earth ion or Y) compositions belong to class of strongly frustrated antiferromagnets. Their crystal structure is build up of alternating Kagome and triangular... -
Partial freezing of a Kagome Magnet
Ever since the first published consideration of the ground state of a triangular lattice of Ising spins by PW Andersen in the 50's, the pursuit of materials with geometrically... -
High pressure charge and magnetic transitions in PbCrO3
The high pressure perovskite PbCrO3 has been known since the 1960s but the electronic properties were controversial. The average structure is a cubic Pm-3m perovskite but a... -
Structure of a 2D antiferromagnet under pressure
Magnetic superexchange is strongly dependant on the degree of orbital overlap and hence the interatomic distances and angles within a structure. One way of tuning magnetic... -
Multiscale studies of crystallisation in stereoregular polypropylenes
We will exploit the unique capability of NIMROD to bring new understanding to the way in which long chain polymers, specifically stereoregulqr polypropylenes, crystallise. There... -
High-pressure neutron diffraction studies of valence transitions in ACu3Fe4O12
Two new A-site ordered perovskite structure oxides, CaCu3Fe4O12 and LaCu3Fe4O12, were recently synthesized under high-pressure and high-temperature conditions in Kyoto. These... -
Variable temperature study of frustrated magetism in Lu2Mo2O5N2
Geometrically frustrated S= 1/2 magnets are of great interest as they do not show classical long range magnetic order at low temperatures and can adopt exotic quantum spin... -

We plan to continue our previous investigation on the influence of thin Mg insert layers on magnetism at buried interfaces in structures that model the lower electrode/barrier... -
Equation of state of ice VI
Ice VI is likely to be a major mantle mineral in the interiors of large icy moons in our solar system, and in large icy extrasolar planets. It is also a common accessory phase... -
Reverse Monte Carlo study of Silicon anode materials for Lithium-ion batteries
The performance of current commercial Li-ion batteries with graphite anodes is limited by the relatively small amount of lithium that can reversibly intercalate between the... -
