Understanding pressure-driven structural changes in FePO4-II
The room temperature high pressure behaviour of FePO4-I has been investigated and a phase transition at around 2.5 GPa to the orthorhombic phase (FePO4-II) accompanied by a... -
Understanding pressure-driven structural and magnetic properties in LaFeO3
This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
High pressure behaviour of ammonium carbamate
A number of compounds crystallise in the NH3-H2O-CO2 ternary system, including ammonium carbonates and carbamates, these being closely related to the water-deficient compound... -
The PVT equation of state of D2O ice III / IX
The high-pressure form of solid water, ice III, is the equilibrium phase in contact with liquid water at pressures from about 2.0 - 3.5 kbar. Consequently, its properties are... -
Searching for the missing phase of SrTiO3; commissioning a new cryogenic pres...
Generating pressure above 1GPa for neutron diffraction typically requires the use of a Paris-Edinburgh press. Whilst the presses operate very reliably at ambient temperature,... -

Our previous PEARL experiment (RB1810619) on LTL zeolite with fluorinert as a pressure-transmitting fluid contradicts the data we collected using silicon oil as... -
Interplay of magnetism and superconductivity in the iron-based spin ladder Ba...
Iron-based superconductors (FeSCs) have been an essential research area in condensed matter physics. Spins of iron sites forming a long periodic configuration, called the... -
Incompressibility, crystal structure and Anderson-Grüneisen parameter of orth...
The ambient-pressure Pnma phase of NiSi is a technologically important material used to form contacts in microelectronics. Recently we carried out the first study of NiSi at... -
Forcing Sr2NiO2Cu2Se2 into the low spin regime under pressure
This is a proposal to drive the layered oxide chalcogenide Sr2NiO2Cu2Se2 from the high-spin state with long range magnetic order to the low-spin state, similar to that displayed... -
Pressure driven phase transitions in the magnetically frustrated layered mate...
Frustration occurs in materials where antiferromagnetic (spin up and spin down pairs) are incomparible with the underlying crystal morphology, for example where the connectivity... -
High Pressure Driven Spin States in LaCoO3
This proposal is concerned with determining variations in the high pressure structure of LaCoO3 and observing changes within this as the material undergoes some well... -

This proposal is concerned with determining variations in the high pressure crystallographic and magnetic structure of LaFeO3. LaFeO3 is a characteristic example of... -
Pressure-induced high-spin low-spin transition in MnS2 and MnTe2
Pressure induced high-spin (HS) to low-spin (LS) transition in MnS2 was speculated by Chattopadhyay and von Schnering more than twenty years ago from their high pressure X-ray... -
High-Pressure Investigation of the Ferroelectric ND4IO3
We propose a high-pressure neutron powder diffraction study of the crystal structure of deuterated ammonium iodate, ND4IO3, which is known to undergo a ferroelectric phase... -
A High pressure investigation of the Manganese Carbonyls Mn(CO)5(CH3) and Mn(...
Organometallic compounds play an important role in catalysis, and compounds with metal carbonyl groups have been studied at elevated pressure by vibrational spectroscopy, but... -
Pressure-temperature phase diagram of of the Jahn-Teller transition in LaMnO3
The parent compound LaMnO3 of the hole-doped colossal magnetoresistance materials La1-xAxMnO3 (A = Ca, Sr, Ba etc.) has attracted much interest from condensed matter scientists.... -
High pressure phase transitions 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... -
Pressure Tuning of Sodium Battery Materials: PART II
This is a continuation proposal to the previous study (RB. 1720418) of NaCoO2. Even if the data analysis is still under process, the result could indicate that the transition... -
High-pressure studies of energetic co-crystals and salts
This proposal will explore the effects of elevated pressures and temperatures on the structures of an energetic co-crystal [CL-20:0.5 HMX] and an energetic salt containing... -
