One of us has recently found experimental evidence for unconventional superconductivity in a newly synthesized three-dimensional nearly antiferromagnetic metal, LaAg1−xMnx...

Recently we have carried out inelastic neutron scattering measurements on Li2RuO3 to understand the nature of the phase transition at 550K. We have seen a clear inelastic...

Geometrically frustrated antiferromagnet LuBaCo4O7 exhibits unusual competition between two low-temperature phases with orthorhombic and monoclinic symmetry. Depending on...

We propose to perform neutron diffraction experiments on a powder sample of a multiferroic hexaferrite PbFe12O19. A recent paper has reported room temperature multiferroic...

We propose to perform high resolution neutron diffraction on powder samples of the frustrated antiferromagnets Ag1-xCuxFe1-yGayO2 using HRPD. CuFe1-yGayO2 and AgFeO2 have...

Because of the potential applications of multiferroicity, the discovery of a new multiferroic (MF) material is invariably met with great enthusiasm in the condensed matter...

Ru4+ ions in Li2RuO3 are on a bipartite lattice and have an orbital degeneracy. The four electrons of the magnetic Ru4+ ions in the threefold-orbitally degenerate t2g manifold...

Geometrically frustrated antiferromagnets RBa(Co/Fe)4O7 (R=rare earth or Y) exhibit a weak ferromagnetic component in the high-temperature spin-liquid phase. Based on a symmetry...

With fantastic flux gains over its liquid conterpart, a solid methane moderator is essential to the newly built Second Target Station at ISIS. Unfortunately, it is notoriously...

We propose to study the newly synthesized compound Cu3Bi(SeO3)2O2Cl, related to the mineral francisite, using neutron diffraction for the first time. This compound is a new...

The new compound Li3Mg2RuO6 exhibits interesting structural and magnetic properties. The Ru5+ sublattice is intrinsically frustrated : chains, along various [110] directions, of...

Superconductivity and the charge density wave (CDW) are two very different cooperative electronic phenomena. However, both occur because of Fermi surface instabilities and...

Test of the NIMS low temperature pressure cell on WISH.

S=0.5 kagome antiferromagnets (KAFM) provide the most promising model system for realising the Resonating Valence Bond (RVB) state. Several S=0.5 KAFM materials are currently...

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

In SrEr2O4 the magnetic Er ions are linked through a network of triangles and hexagons, where geometrical frustration can arise, provided that some exchange interactions are...

Back up experiment to fill gap in the schedule if beamtime is available

-Fe3Sn2 is a rare example of a ferromagnetic metal. It features a giant Anomalous Hall Effect (AHE) at room temperature that makes it a candidate material for spintronics...

A recent addition to the list of emergent materials is the ReBaCo4O7+delta family of compounds. Indeed, due to the magnitude of their oxygen uptake and release capability, they...

Coexistence of magnetic ordering and ferroelectricity in multiferroic materials, especially at high temperatures, is of great technological and fundamental interest. There are...
