A high pressure study of the novel hybrid improper ferroelectric HgMn7O12
We have recently discovered how a novel type of hybrid improper ferroelectricity can arise in the perovskite HgMn3Mn412. This ferroelectricity is driven by a highly unusual... -

The Anderson-Gruneisen parameter and high P/T crystal structure of post-perov...
Recently, our view of the Earth¿s lower mantle changed dramatically. It had been thought that two major phases were present in all the lower mantle: MgSiO3-perovskite (PV) and... -
Thermal equations of state for kyanite, andalusite and sillimanite
The three Al-silicate polymorphs, kyanite, andalusite and sillimanite, are well-known geological markers used to determine the extent of P- and T-induced metamorphism... -
Mechanism of network collapse in strong network glass forming systems
The object of this proposal is to investigate the mechanism of network collapse in the ¿strong¿ network glass forming system GeO2 in the pressure range between 9 and 16 GPa... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Investigation into the “1/8 anomaly” in superconducting cuprates: La2-xBaxCuO...
The superconducting material La2-xBaxCuO4 (LBCO) exhibits an anomalous dip in Tc at the x = 0.125 composition at low temperature (>30 K). This is at odds with other... -
PT-phase diagram of ammonium bromide
Ammonium bromide is a fundamental ionic solid that finds practical use, industrially, as a highly-effective flame retardant and also as an intermediary source of bromide in... -
Insulator to metal transition in TiOCl at high pressures
We propose to study the high temperature structure of TiOCl where a pressure induced metal to insulator transition has been reported recently by Kuntscher et al.Due to our...
