Iron tungstate Fe2WO6 attracts increasing interest in two areas of applications due to its photoelectrochemical behaviour. Fe2WO6 can act either as a photocatalyst for...

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...

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....

We have recently observed extraordinary polymorphism on cooling various sodalites under vacuum. Materials undergo a phase transition followed by a fully reversible...

The aim of the present proposal is to relate the macroscopic magnetic properties with the nuclear and magnetic structure of a series of Ni48Mn36In16-xSnx Heusler alloys. These...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

When isolated spin clusters are weakly coupled to each other, zero-dimensional quantum and three-dimensional collective magnetism concomitantly occur. This is envisioned in the...

This proposal is to probe the structure and magnetic ordering in Sr2CrO2Fe2As2 and Sr2CrO2Co2As2, in order to complete a description of trends in the Cr sublattice magnetic...

The aim of the present proposal is to relate the macroscopic magnetic properties with the nuclear and magnetic structure of a series of Ni48Mn36In16-xSnx Heusler alloys. These...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

The Heusler alloys Ni-Mn-Ga are widely considered as a new generation of multifunctional smart materials due to the mutual interplay between structural and magnetic properties...

We propose to use WISH to examine whether a transition between different spiral antiferromagnetic structures in zero magnetic field is the key to tricriticality at finite fields...

Experiments (many at ISIS) using crystallographic methods, total scattering, inelastic neutron scattering and theory have provided a detailed picture of the origin of strong...

Materials exhibiting giant magnetocaloric effect (i.e. the large temperature change under a magnetic field variation) are the most promising type for magnetic refrigeration....

Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of...

Test of the NIMS low temperature pressure cell on WISH.

Ni-Mn based Heusler alloys are magnetic multifunctional materials currently under intense research efforts thanks to their unique coexistence of a reversible structural...

Highly oxidized iron oxides such as SrFe4+O3, CaFe4+O3, and CaCu3Fe4O12 display unusual electronic and magnetic behaviors due to the highly covalent nature of the Fe-O...

Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect (MVE) in...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...
