For the RMn3O6 manganites, we have shown that tuning A-B exchange, by choice of A-site cation or by doping magnetic impurities, gives rise to dramatically different magnetic...

Our recent study of CaFe3O5 revealed a remarkable discovery of electronic phase separation, similar to examples widely reported in manganite perovskites. Electronic phase...

Ga2-xFexO3 (GFO) is a ferrimagnetic magnetoelectric material presenting a Curie temperature above room temperature for x>1.3. It is therefore an interesting candidate for the...

In recent years there has been a large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

A recent exciting development in magnetic materials was the discovery of a new iron oxide, Fe4O5, using high temperature and high pressure. A very recent structural study has...

Ferroelectricity in type-II multiferroics is induced by breaking of inversion symmetry by certain type of spin structure below the magnetic ordering temperature. Therefore, a...

The National Physical Laboratory (NPL) and the WISH instrument team has worked together to enable simultaneous real-time high resolution (powder and single crystal) neutron...

In oder to understand our universe, we built large research facilities such as the LHC in Switzerland, which can be used to find new particles. In the solid state, such...

A new kind of topologically protected electronic state has been predicted in crystals whose surfaces form atomic patterns with certain non-symmorphic symmetries. Eu5In2Sb6 is...

Multiferroics - where ferroelectric and magnetic orders co-exist - continue to be of technological and scientific importance, and of particular interest are the improper...

Ferroelectricity induced by magnetic ordering with certain type of magnetic structure has received much attention because it provides opportunity to manipulate magnetization by...

Ni rich layered oxides are promising cathode materials for Li-ion batteries since they fulfil the energy density requirements of the automobile industry but they tend to degrade...

Manganese based oxides are of great interest for both spintronic and multiferroic applications.Pb2MnO4 crystallizes in the acentric but non-polar space group P-421c which allows...

Test of the NIMS low temperature pressure cell on WISH.

The spin Jahn-Teller effect stabilises 3D magnetic order in an otherwise frustrated system via magnetoelastic coupling, spontaneously at the magnetic phase transition. Examples...

We propose to perform neutron diffraction experiments under high-pressure on multiferroic TbMnO3 using WISH in combination with hybrid-anvil-type high-pressure device. Recently,...

This study is designed to identify relationships between structure and magnetic properties characteristic of coordination polymers (CPs). By determining the ground state 3D...

Understanding the magnetic structure of the perovskite manganites has been a significant field of research over the past 20 year due of their numerous technologically relevant...

Preliminary bulk measurements show that Ba(TiO)Cu4(PO4)4 is a potentially exciting candidate for studies of low-dimensional magnetism. However, currently relatively little is...

We propose to perform neutron diffraction experiments under high-pressure and magnetic field condition for multiferroic DyMnO3, using WISH beamline in combination with...
