Negative thermal expansion in the rutile phase of ZnF2
It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this... -
Proton dynamics in novel organic ferroelectric materials
The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in... -
Thermal expansion and phase transition in magnesium sulfate trihydrate
A recent single-crystal study determined the crystal structure of MgSO4.3D2O, and discovered that a first-order phase transition occurs when the crystal is cooled below 245 K.... -
Is dynamic asymmetry the essential ingredient in the (universal?) 'strong-fra...
We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the... -
Molecular dynamics and melting in CH3NH3PbCl3:
The organic-inorganic perovskites (CH3NH3Pb(Br,Cl,I)3) have been identified as efficient photovoltaic materials. Theoretical calculations have suggested that the low energy... -
Morphology-activity relationships in catalysis promoted by MoOx nanoparticles
Metal and metal oxide nanostructures can be prepared in much different morphology (nanowires, nanobelts, nanofibres etc.) which are known to exhibit better adjustable properties... -
INS studies of molecular hydrogen in K-doped electrospun graphite nanofibres
The physisorptive capacity of graphite-based nanomaterials for hydrogen is strongly dependent on their internal surface areas and pore dimensions. We have made electrospun... -
Multiferroic (Ferroelastic/Magnetic) Phase Transitions in KMnF3
KMnF3 perovskite undergoes 3 structural, and two magnetic phase transitions on cooling from 300 K to 2 K. Above 185 K the compound is in the aristotype structure, on cooling... -

This experiment will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to correlate magnetic and... -
Structural phase diagram of rare earth substituted multiferroic BiFeO3 - revi...
BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We... -
Study of magnetic spiral in the room temperature multiferroic BiFeO3 - PbTiO3
BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature... -
Effects of external and chemical pressure on the magnetovolume effects in Ba3...
Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound.... -
The structural phase transitions of Ammonia Borane, an invetigation of the dy...
Ammonia Borane (AB), NH3BH3, was first synthesised in the 1950s and has now become the focus of a world wide research program with regards to its potential as a hydrogen store.... -
Low-temperature incommensurate magnetic structure study of magneto-dielectric...
The interplay between spin, charge, orbital, and lattice degrees of freedoms in SrMn1-xWxO3 (X= 0.1625, 0.175) produce the charge and/or spin density waves (CDW, SDW) modulated...
