We propose to study a layered oxide in which chromium cations describe a triangular array. Itseems us that no magnetic data are reported up to now for this alpha-CaCr2O4...

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...

This proposal is to observe single-spin diffusive motion on a two-dimensional (2D) percolating network having a fractal geometry. The random walker¿s travel times on a...

Despite the importance of the LiFeO2 phases as cathode materials in lithium ion batteries, little is known about their crystal structures, except that they should be based on...

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...

New perovskite phases containing lead and halogens with a molecular cation are providing new options for materials in solar cells, giving unusually high efficiencies in...

Very recently, the metastable cubic ice phase was renamed to stacking-disordered ice (ice Isd) in order to emphasise the fact that this form of ice contains not only cubic...

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...

Building on our preliminary neutron transmission results from the CRISP instrument (see below), we propose to undertake a detailed study of critical fluctuations in 3He near its...

Every new triangular lattice (TL) antiferromagnet attracts considerable attention since they usually display rich physics due to the inherent frustration and degenerate ground...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

This experiment will investigate three related systems which contain copper deficient anti-fluorite-type copper sulfide layers. The overall aim is to correlate magnetic and...

BiFeO3 is the most widely studied multiferroic and rare earth doping overcomes problems associated with phase metastability and leakage which have hampered applications. We...

Ba3BiIr2O9 and Ba3BiRu2O9 undergo very unusual structural transitions at 74 and 176 K respectively, with instantaneous negative thermal expansion of up to 1% in the Ir compound....

Ammonia Borane (AB), NH3BH3, was first synthesised in the 1950s and has now become the focus of a world wide research program with regards to its potential as a hydrogen store....

The interplay between spin, charge, orbital, and lattice degrees of freedoms in SrMn1-xWxO3 (X= 0.1625, 0.175) produce the charge and/or spin density waves (CDW, SDW) modulated...

Halogenomethane derivatives exhibit thermally induced solid¿solid phase transitions before melting that are attributed to the ability to gain rotational degrees of freedom in...

The physical properties of the post-perovskite phase of MgSiO3 control the dynamics of the lower thermal boundary layer of the Earth¿s mantle, but many of these properties...
