Revising the onset of anharmonicity in proteins
Our previous INS studies of ¿dry¿/hydrated apoferritin show that the hydrated protein undergoes a dynamical transition, Td, at 200K. Such behavior, first modeled by Doster et al... -
Suppressing long axis intermolecular vibrational modes in molecular semicondu...
The van der Waals nature of carbon based organic semiconductors (OSCs) offers low cost deposition routes while intermolecular vibrations affect to some extend their charge... -
Unravelling the origin of high-temperature magnetic bistability in dysprosoce...
In the last 25 years the highest blocking temperature TB achieved for the best performing molecular nanomagnets has only reached few K. The situation has recently changed... -
Thermal fluctuations of cold shock proteins from different flavours of extrem...
Extremophiles are organisms which survive and thrive in extreme environments. The proteins from extremophilic organisms have received considerable attention as they are... -
Phase Separation and Jahn Teller Distortion in Molybdate Perovskites
Two days of beamtime on HRPD will be used to examine a family of double perovskites Sr2YbMO6 that are isostructural at room temperature. When M = Mo5+ the monoclinic perovskite... -
Magnetic properties of quadruple perovskites containing A- and B-site iron ca...
New quadruple perovskites with nominal compositions LnFe4Ti3O12 (Ln = La, Nd) have recently been discovered through high pressure synthesis. Mössbauer spectra show that these... -
Can we use the H-H stretch of adsorbed dihydrogen to characterise materials?
The use of the J 0-to-1 rotational transition of dihydrogen has been extensively used to characterise the state if hydrogen in and on materials. The disadvantage of studying the... -
Topological Phase Transitions Driven by Magnetic Phase Transitions in FexBi2Te3
Topological insulators are currently a subject of intense research and potential for spin-electronic devices. The breaking of gauge symmetry or time reversal symmetry(TRS) is a... -
Copy of: Structural and Magnetic Studies of Mixed-Valence Iron Silicates
We propose to study the temperature evolution of the spontaneous strain, crystal and magnetic structure of the charge ordered, mixed valence iron silicate ilvaite. In addition,... -
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... -
Me-ND311BD4: a temperature dependent study of its crystal structure and decom...
We request 4 days on HRPD with the IGAn apparatus to follow the structural changes of Me-ND4 11BD4 as a function of temperature. The high resolution of HRPD will allow us to... -
Inelastic neutron scattering and musr studies of the high-distorted double pe...
The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic... -
Correlation of structure and magnetic ordering with composition in layered co...
We propose to use OSIRIS to determine the magnetic structures of a series of cobalt oxysulfides containing Co in square planar coordination. Several compositions... -
Magnetic structures of antiferromagnetic heavy fermion CeAuAl3 and CeCuAl3 co...
CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of... -
What is the cause for the gapped mode in the `BEC' phase of DTN?
Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an... -
