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...

Transition metal pyrovanadate M2V2O7 (M = Ni, Co, Mn) exist with a great variety of crystal structures, which are reflected in the richness of their physical properties....

The rare earth iridates, R2Ir2O7 have been intensely studied in recent years due to the unique behaviour of the magnetism on the iridium sites; a consequence of competition...

Novel functionality in condensed matter physics is one of fastest developing fields, aiming for possible future applications including quantum computing, electronic devices and...

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

Similar magnetic excitations have been observed in high-transition-temperature (high-Tc) cuprates by time-of-flight neutron spectrometer, namely, a characteristic hourglass-like...

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

BiFeO3 is a room temperature multiferroic, displaying both ferroelectric and antiferromagnetic (AFE) ordering. x-BiFeO3 - (1-x)-PbTiO3 is also multiferroic at room temperature...

Magnetic frustration - the inability to mutually satisfy all magnetic interactions in a system - is the source of many interesting phenomena, including spin liquids and ices. In...

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 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...

Fast segmental dynamics of surfactants in rod-like assemblies and their correlation with microstructure is not very well understood although the structure and macroscopic...

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...

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

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...

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...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

Back up experiment to fill gap in the schedule if beamtime is available

We propose to measure the collective spin excitations over a wide energy range in BaFe2-xCoxAs2 (x=0.22). This compound is one of the FeAs based superconductors which have...
