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

Test of the NIMS low temperature pressure cell on WISH.

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...

We plan to investigate the low-temperature structure and magnetostructural coupling in PdCrO2, which is a quasi-2D material with strongly anisotropic physical properties. It is...

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...

Non-coplanar magnetic orders in metallic helimagnets have been of great interest since the discovery of a vortex-like spin-swirling object called "skyrmion" and the resulting...

Recently, our combined diffraction and NMR experiments have shown that alpha-NaMnO2, an antiferromagnet with two-dimensional triangular stacked topology, is a striking example...

Based on old data and the recent litterature, we suspect the existence of a poorly documented low temperature magnetic phase transition (T<30K) in colossal magnetoresitve...

The control of physical properties through cation ordering in perovskites often gives rise to unexpected and desirable functionality. Of particular interest in the preparation...

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

The recently discovered hybrid lead iodide materials have captured significant attention due to their application in highly efficient solar cells. The fact that these materials...

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...

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...

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...

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

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...

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

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...

The AA'$3$Mn$_4$O${12}$ family of manganites with quadruple perovskite structure has recently attracted a lot of interest as a disorder-free model system for many of the...

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...
