We request 5 days on IRIS to investigate the hindrance to molecular rotation of ammonia in a zeolite framework due to hydrogen bonding interactions. This is a tied proposal to...

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...

Hybrid organic-inorganic perovskites are interesting candidates for a range of applications, from solar cells to light emitting diodes and lasers. For the latter applications...

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...

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...

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....

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

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...

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...

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....

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...

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...

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 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...

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...

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...

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...

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...
