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

The rare-earth oxides of the general formula A2B2O7, with A being a rare-earth ion (Er in our case) and B a d- or p-metal (B = Zr or Ir), have been extensively studied for their...

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 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...

Sr3Ru2O7 is a layered Ruddlesden-Popper perovskite which displays intriguing behaviour at low temperatures and high magnetic field. It can be tuned close to a quantum critical...

With the overall aim of extending the information derivable in a neutron single crystal diffraction experiment beyond the static structure, we are proposing to perform a...

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...

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 family of guanidinium metal formates has the perovskite structure and, like many perovskites, is of interest for these materials¿ magnetic and electric properties, in...

YbAgGe has an enhanced electronic specific heat coefficient and two magnetic phase transitions at TM1=0.8K and TM2=0.65K. We have grown a series of TbxYb1-xAgGe and YbAgGe...

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...

This proposal is to explore the evolution of magnetic ordering in two members of the homologous series CaFe2O4(FeO)n with n = 1, & 3, and to correlation the behaviour of the...

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...

In 2010 several groups showed that iron selenide, already a superconductor at 8 K, could be charged with alkali cations leading to higher critical temperatures. These compounds...

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...

The occurrence of multiferroic properties in incommensurately charge and magnetic ordered phases in the narrow band Pr1-xCaxMnO3 has freshly steered the search of newer such...

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...

Lu and Ho counterparts of RE3Fe5O12 will be an appropriate platform to reveal the complexmagnetic ground state of rare earth iron garnets with common formula RE3Fe5O12. Lu3+...

Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice in spin pumping, spin Seeback and Spin Hall magnetoresistance (SHMR) measurements [1-3]. This is mainly due to two...
