Neutron spin resonance mode is a common feature in different classes of magnetic superconductors; nonetheless, the microscopic origin of the mode is still unclear. In general,...

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...

The crystal structures and magnetic ordering of layered compounds that have been modified by low temperature chemical methods will be probed using neutrons. The systems...

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...

We will study H2 dynamics in the nanotubular clay imogolite whose structure has an external diameter of ~2.5 nm and an inner diameter of <1 nm. The tube length of synthetic...

The recently designed CPO-27-M, where M=Mg,Mn,Fe,Co,Ni, and Zn represent a family of metal-organic framework compounds with the highest density of coordinatively unstaurated...

This study is designed to identify relationships between structure and magnetic properties characteristic of coordination polymers (CPs), specifically in the model system...

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...

Back up experiment to fill gap in the schedule if beamtime is available

Metallic hydrogen has long been theorised to be a close-to-room temperature superconductor, but is only predicted to form at GPa pressures. Instead of using extremely high...

An interesting family of Cu (II)-framework (NOTT100 series) has been synthesized at the University of Nottingham by the group of research of Martin Schröder. Earlier studies on...

We request 3 days on TOSCA to study molecular rotations of NH4+ and BH4- ions and the ionic disorder in ammonium borohydride (rock salt lattice) and its methylated derivative....

FeSe has a superconducting ordering temperature Tc = 9K. Superconductivity coexists with nematic order which is manifest most clearly by an orthorhombic distortion which sets in...

Flexible metal-organic frameworks (MOFs) such as Zn(C3H3N2) (ZIF-4) and Cu2(BBCDC) (DUT-49) show intriguing structural phase transitions when triggered by external stimuli such...

We would like to complete the phase diagram by measuring one more sample of Fe1+xTe for x = 14 %, which represents a point at one extreme of the phase diagram. The simple binary...

Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice for spin Hall related effects, magnonics, inter alia and has been used in microwave applications for many years....

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...

Chemical substitution is a valuable technique for probing the behaviour of materials since this exerts a stress comparable in many respects to changes in pressure or...

The miscibility of polycarbonates (PC) with polystyrene (PS) appears to be closely related to chain dynamics. Among all polycarbonates, tetramethyl bisphenol-A polycarbonate...

Spin ices are exotic phases of matter characterized by frustrated spins obeying local “ice rules” that minimize the number of spatially isolated magnetic monopoles, in analogy...
