Magnetic structure of pyrochlore irridate Y2Ir2O7
We propose to study by powder neutron diffraction the ordered magnetic state of the pyrochlore compound Y2Ir2O7. There is currently an increasing interest in the condensed... -
Continuation: Metastable Water Ice and Nitric Acid ¿ observing the phase changes
Nitric acid plays important roles in the atmosphere, in all aggregate states and combined with water.During the last periode we were running the proposal RB1110207 "Metastable... -
Study of the protein denaturation in glassy matrices
The proposed experiment is addressed to use the MARI spectrometer to study the thermal denaturation process of the psychrophile enzyme alpha-amylase in presence of bioprotectant... -
From giant magneto-elastic coupling to negative thermal expansion
We recently used high-resolution neutron diffraction on HRPD to observe the largest magneto-elastic coupling ever seen in a metallic magnet. The material studied was CoMnSi, a... -
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... -
PDF study of the structural disorder in a quantum spin liquid candidate
We have identified a potential quantum spin liquid by tuning the magnetic interactions on a square lattice through d10-d0 cation mixing. MuSR shows dynamic magnetism down to... -
Investigation of the low temperature phases of SrSnO3
The present proposal is to examine the low temperature structural properties of SrSnO3 using the HRPD. This work aims to examine the structural basis for the unusual low... -
Structure, thermal expansion and vibrational properties of ammonium bicarbona...
Ammonium carbonates, sensu lato, have relevance to carbon capture schemes and as potential hydrogen storage materials. These compounds occur on Earth as minerals and, since... -
Partially disordered antiferromagnet phase of CsCoX3 (X=Cl, Br)
Systems of the CsCoX3 family form antiferromagnetic chains along the c-axis, and are arranged in a frustrated triangular arrangement in the ab-plane. Below 30K, both systems... -
Phase Separation in NaTaO3. Can it be controlled by pressure?
The present proposal seeks to establish the pressure dependence of the Pbnm-Cmcm transition in NaTaO3 and some doped variants thereof. It aims to understand the understand the... -
Investigations of amorphous pharmaceutical materials produced from different ...
Pharmaceuticals are usually formulated in the crystalline state for obvious reasons of stability. They may also exist in a disordered and less cohesive state i.e. amorphous... -

Magnetic ordering and an extraordinary anomalous Hall effect in the itinerant...
-Fe3Sn2 is a rare example of a ferromagnetic metal. It features a giant Anomalous Hall Effect (AHE) at room temperature that makes it a candidate material for spintronics... -
The role of Disorder in Phase Transitions in some manganese Perovskites
The aim of this work is to understand the origin of the difference in the behaviour between the two doped manganites Sr0.65Pr0.35MnO3 and Sr0.70Ce0.30MnO3. The hypothesis we... -
Searching for chiral bobbers in B20 FeGe epilayers
Chiral magnetism in non-centrosymmetric systems that have a strong Dzyaloshinskii-Moriya interaction is a burgeoning field, with chiral skyrmions attracting enormous interest.... -

Hydrogen Peroxide is one of the cleanest, most versatile strategic base chemicals available. It is used at the large scale as oxidising agent in the chemical industry, as a... -
Configurational and displacive disorder in the cubic NTE material Cd(CN)2
Cubic cadmium(II) cyanide shows the most pronounced isotropic NTE effect known, with behaviour more than twice as extreme as that of better known materials such as ZrW2O8. This... -
The effect of redox on the substitution mechanism of Ti in meteoritic hibonite
We request 3 days of beam-time on HRPD to identify the substitution mechanism of Ti3+ and Ti4+ in synthetic hibonites [CaAl12O19]. The experiment forms part of a larger... -
Polycarbonate and tetramethyl bisphenol A polycarbonate
The miscibility of polycarbonates (PC) with polystyrene (PS) appears to be closely related to chain dynamics. Among all polycarbonates, tetramethyl bisphenol-A polycarbonate...
