The aim of the present proposal is to experimentally investigate the magnetic order below Tc in the cubic quasicrystal approximant Au5.027Si1.307Tb, which orders ferro- or...

Exchange bias (EB) effect, characterized by a shift of the hysteresis loop along the magnetic field axis, has attracted considerable attention because of its significance in...

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...

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...

Hexaferrites are well known for their applications as permanent magnet and memory devices. In recent years, the interest in hexaferrite has grown from the point of view of...

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.

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...

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...

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...

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...

Yttrium iron garnet Fe3Y5O12 (YIG) is the material of choice for spin Hall related effects, magnonics, inter alia and has been used in microwave applications for many years....

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...

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...

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...
