In recent years there has been a growing interest in modifying the anion lattice of complex transition metal oxides, via topochemical manipulation, to tune the magnetic and...

Iridium oxides are of interest because many novel magnetic phases have been predicted in crystals, depending on the geometry of the crystal lattice. Our proposal concerns two...

Experiments (many at ISIS) using crystallographic methods, total scattering, inelastic neutron scattering and theory have provided a detailed picture of the origin of strong...

A relaxor ferroelectric exhibits a net polarisation only in an applied electric field due to the co-alignment of polar nanoregions. In La3Ni2SbO9 we found the magnetic...

The experiment will study the magnetic structure in the complex boride Mn3Co20B6. Substitutions in this compound makes it possible to tune the magnetic properties, thus, making...

Incommensurate magnetic phases generated by frustrated magnetic exchange interactions can stabilise novel induced magnetoelectrics. We have recently found that the...

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 composition Ni2.04Mn1.4Sn0.56 belongs to the group of metamagnetic shape memory alloys and it shows multiple magnetic phases as a function of temperature. In a recent muon...

Materials exhibiting giant magnetocaloric effect (i.e. the large temperature change under a magnetic field variation) are the most promising type for magnetic refrigeration....

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...

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

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...

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...

Test of the NIMS low temperature pressure cell on WISH.

Ni-Mn based Heusler alloys with composition related to the stoichiometry Ni2MnX, with X belonging to the IIIA-VA chemical species, are widely considered as a class of...

Negative thermal expansion (NTE) materials, the volume of a material abnormally contract with the increase of temperature, is closed related to the magnetovolume effect (MVE) in...

The late first row transition metal monoxides are the canonical antiferromagnets. Their magnetic structures were first determined many decades ago but contemporary studies have...

We will carry out a definitive local structure investigation of the ferroelectric transition in [ND4][Zn(DCOO)3]. This compound is seen as the canonical example of a...

Magnetic equiatomic alloys (MEAs) of the general formula MM'X (M, M' = transition metals, X = Si, Ge, Sn) undergo magnetostructural transition of martensitic type on cooling...

ZrMn2H3 is a Laves Phase intermetallic hydride with interesting materials properties - unlike most Laves Phases, the parent alloy ZrMn2 is not a line phase but has a wide range...
