It has recently been discovered than the rutile phase of zinc fluoride shows negative thermal expansion along all three crystallographic axes. What is highly unusual about this...

The vast majority of known ferroelectrics are inorganic compounds such as barium titanate and potassium dihydrogen phosphate. Contrary to naïve expectation, ferroelectricity in...

We want to elucidate whether the so-called ¿strong-fragile¿ transition reported for water mixtures is a universal phenomenon driven by confinement effects originated by the...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

Manganites show promise as magnetocaloric materials - for use in solid-state refrigeration - in terms of cost, durability and tunable thermal conductivity. By tuning the...

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 request 4 days on IRIS to investigate the diffusional and rotational dynamics of the alkalide forming, fully methylated aza-crown hexamethyl-hexacyclen (HMHC) in...

YbPd crystallizes in the cubic CsCl-type structure and reported to have magnetically ordered ground state with the mixed valence of the Yb ion. Further, it under goes through...

Multiferroics and in particular BiFeO3 have recieved alot of interest. The potential of multiferroic materials to be incorporated into many devices such as sensors and memory...

We request 6 days on IRIS to study the diffusion of adsorbed gas molecules (H2, CH4, C2H2, C2H4, C2H6) within a functional porous metal-organic framework (MOF) as a function of...

The undecahydrate of magnesium sulfate (meridianiite) is likely to occur a major rock-forming mineral in the interiors of large icy satellites such as Ganymede, Callisto and...

The defect thiospinel, GeV4S8 adopts a cubic structure at room temperature (space group F-43m). We have identified a new monoclinic phase of this material at 2K, which may be...

A reliable spectroscopic assignment of the high-frequency proton modes in CsH2PO4 (CDP) is possible only within the framework of the fully ordered proton, low-temperature P21...

The objective of this proposal is to solve the field-induced magnetic structure of a newly synthesized brownmillerite. Under normal conditions there are three different magnetic...

This proposal seeks to investigate the effect of temperature on the structures of thallium and caesium azide. High-resolution neutron powder diffraction data are necessary to...

20 years ago, Anderson proposed that the thermoelastic properties of the dominant (mantle) phase within the Earth, MgSiO3 perovskite, could be described as a simple Debye solid....

High resolution powder diffraction data will be used to obtain lattice parameter and atomic coordinate variations as a function of temperature for Pr0.6Ca0.4MnO3, which has a...

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...

NaFe0.53Cu0.47As is an antiferromagnetic Mott insulator which connects unconventional superconductivity and Mott physics. The magnetic fluctuations in the ordered state has been...

Strong magnets with a high energy product are vital when optimizing the efficiency in the electricindustry. This can be achieved by making spring-exchange coupled magnets....
