Internal stresses in superconducting bulk magnets studied by in situ neutron ...
Bulk high temperature superconductors are useful for permanent magnet applications because they can generate much stronger magnetic fields than ferromagnets and are more compact... -
The magnetic structures of RMn7O12 (R = Nd, Sm, Dy, Y)
Materials with the perovskite crystal structure are ubiquitous in condensed matter physics. Despite being known for several years, the quadruple perovskites, which afford... -
The magnetic structure of an A- site and B-site ordered perovskite: CaCu3Fe2O...
Recently, double perovskites have attracted enormous attention. Now, we have successfully synthesized a quadruple perovskite compound which shows not only one but, both, A-site... -
Li(MeNH2)4: Poor Metal, Worse Metal, and Magnet
We request 2 days on GEM to determine the structure of crystalline Li(MeNH2)4: we will be preparing the fully deuterated analogue. Our investigations into the magnetic state of... -
Order and disorder in (Mn,Fe)2(P,Si) magnetocaloric compounds
In the high-performance and low-cost (Mn,Fe)2(P,Si) magnetocaloric compounds, the detrimental hysteresis has been significantly reduced by balancing Mn:Fe and P:Si ratios, which... -
Structural Phase Diagram of the new Multiferroic Hexagonal YbFeO3
This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room... -
Subtle magnetic phase transitions in multiferroic BiFeO3
This experiment seeks to probe the magnetic structure of multiferroic BiFeO3 and its evolution on lowering temperature, with the specific aim of identifying magneto-structural... -
Dynamical Transitions in the Ogg Glasses
We request 4 days on IRIS to study the temperature dependance of the structural dynamics in amorphous sodium-ammonia (Na-NH3). This will be the first investigation of the... -
Principal Component Analysis of Phase Behaviour on the Upgraded TOSCA
Principal Component Analysis (PCA) is a powerful chemometric tool for the analysis of multivariate datasets. Capitalising from the recent upgrade of the TOSCA spectrometer, we... -
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... -
Further studies of the Mg(BH_{4} )_{2} and parahydrogen
We found evidence of solid para-hydrogen absorbed in Mg(BH_{4} ){2} up to temperatures of 195 K. Para hydrogen was dosed in Mg(BH{4} )_{2} at 50 K. A series of dosings were... -
Texture memory and variant selection for steel and titanium and zirconium alloys
The proposed experiment will focus on determining the level of texture memory and variant selection on both heating and cooling for steel and titanium and zirconium alloys with... -
Structural and Magnetic Characterizations of the New, High Pressure Synthesiz...
After an almost forty year lull in research on multiferroic materials, there has been a resurgence of interest in them. However, it is particularly challenging to synthesize a... -
Tuning cycloidal ordering by epitaxial strain in BiFeO3 thin films
Owing to their promising applications, especially in spintronics, multiferroics have been at the fprefront of condensed matter research for a number of years. In these...
