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...

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...

The exotic physics of low-dimensional quantum magnets has recently been highlighted by the award of a Nobel Prize to Duncan Haldane. We have identified the molecular framework...

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...

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...

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...

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

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...

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 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...

Cerium and ytterbium are two members of the lanthanide (rare earth) series of elements that haverevealed in their intermetallic compounds new physics and many interesting...

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...

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

We propose to use WISH to examine whether a transition between different spiral antiferromagnetic structures in zero magnetic field is the key to tricriticality at finite fields...

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