Novel functionality in condensed matter physics is continuously attracting huge attention owing to the possible novel future applications including quantum computing, electronic...

Recently we have investigated magnetic and quadrupolar ordered states of YbRu2Ge2 using zero-field muon spin relaxation (µSR), neutron diffraction and inelastic neutron...

We had been given 1 day of beam time on WISH, RB1710144, to investigate the magnetic structure of T2V2O7 (T=Mn, Ni, Co) We performed power neutron diffraction measurements on...

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...

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

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...

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

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...

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...

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

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...

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

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...

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...

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

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

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

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,...

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