This proposal would like to map the diffraction patterns of Gd3Al5Gd12 (GAG) using the high flux diffraction instrument WISH. It is of great interest to solve the magnetic...

TbMnO3 attracts special attention due to its large magnetoelectric coupling, polarization flop and ferro-paramagnetic phase transition, both induced by magnetic field. Despite...

In a previous WISH experiment, we have succeeded in determining the incommensurate cycloidal magnetic structure of AgFeO2, which induces a ferroelectric polarization[1]....

The crystal structures of Ba2(Co,Ni)OsO6 compounds have been refined using a combination of high- resolution S-XRD (collected at the Australian Synchrotron) and NPD...

Metastable multiferroic perovskites of the BiFe1-xScxO3 system, stabilised by high-pressure and high-temperature synthesis, demonstrate irreversible phase transformations upon...

This proposal forms part of our project to investigate the implications of non-trivial real-space topology in multi-k magnetic structures. We are here focusing on the rare earth...

We aim to utilise Low-Energy Neutron Scattering (LENS) at OSIRIS to investigate the effects of gas adsorption on the quantum rotation of the methyl groups present in a Metal...

We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

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...

We propose to perform a neutron diffraction experiment under magnetic fields using a single crystal sample of multiferroic alpha-NaFeO2 on WISH beamline. Recently, we have...

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 superexchange interaction - in which the intervening oxygen mediates magnetism between two partially filled d shells- is well described by the semi-empirical...

Emerging technologies require increasingly unusual functional materials and so understanding the origins of complex magnetic and electronic behaviour, and how these can be...

High pressure is a powerful thermodynamic tool, like temperature, to vary the properties and structure of materials. X-ray and neutron diffraction can be used to measure certain...

Three new doubly ordered perovskites NaYMWO6 (M=Mn, Co & Ni) have been synthesized by high pressure and high temperature. Analysis of room temperature laboratory X-ray...

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...

Purely ferromagnetic (FM) oxides are uncommon but we recently reported FM behaviour in a mineral induced by quite small magnetic fields. This ability relates to the presence of...

Local magnetic interactions in lanthanide compounds have recently been shown to tune their entropically driven magnetocaloric effect (MCE), useful for magnetic coolants. In this...

Perovskite-type compounds can be both very simple and tremendously complex. Remarkably, even binary perovskite-type compounds may exhibit high level of complexity that leads to...
