Polaron-mediated colossal magneto-resistance (CMR) was predicted decades ago but never been experimentally established unambigously, despite the 'universal' existence of...

Understanding the structures of complex materials is key understanding their properties. Here we wish to determine the structure, both atomic and magnetic, of a complex...

The proposed 1111 system whose structures are largely underinvestigated exhibits properties with a strong potential for novel properties that complement our knowledge of the...

The aim of the present proposal is to relate the macroscopic magnetic properties with the nuclear and magnetic structure of a series of Ni48Mn36In16-xSnx Heusler alloys. These...

The formation of charge and spin density wave (CDW and SDW) states in metallic systems isdriven by Fermi surface instabilities that are often found to compete with...

CeAuAl3 and CeCuAl3 compounds crystallize in the tetragonal I4mm, BaNiSn3-type and display interesting bulk properties. Here we propose to investigate the magnetic structures of...

Although the systems of choice for the study of electronic correlations have traditionally been 3d transition metal oxides, the interest has recently been extended to 4d and 5d...

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...

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 large interest in geometrically frustrated magnetic systems, especially those with spins interacting on two-dimensional triangular lattices...

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...

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.

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...

Ba4Ru3O10 is a rather fascinating compound with quasi two dimensional crystal structure. Although the compound shows strong feature in the magnetization data at 105 K indicating...

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

Our aim is to study with high resolution neutron powder diffraction the two orthorhombic phases of Mn2TeO6 at RT, so as to understand the origin of the observed structural...

Perovskite oxides exhibit a large array of interesting electronic properties. Owing to their difficult synthesis (requiring extremely high pressures) the MOsO3 Osmates offer a...

We have recently prepared a new strontium ruthenate, SrRu2O6, using hydrothermal chemistry. The material shows magnetic order, probably ferromagnetic, than persists above, and...
