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

We propose to perform neutron diffraction experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

We propose to perform neutron diffraction experiment under high pressure condition, using a single crystal of CuO on WISH beamline. This monoxide is known as a multiferroic...

Both 1D physics (dimensional frustration) and geometric frustration offer ways of achieving unusual quantum ground states that defy the usual tendency for systems to order at...

We had been given 1 day of beam time on WISH, RB1710144, to investigate the magnetic structure of T2V2O7 (T=Mn, Ni, Co) We performed power neutron diffraction measurements on...

Recently we have investigated magnetic and quadrupolar ordered states of YbRu2Ge2 using zero-field muon spin relaxation (µSR), neutron diffraction and inelastic neutron...

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

Ferroelectricity in type-II multiferroics is induced by breaking of inversion symmetry by certain type of spin structure below the magnetic ordering temperature. Therefore, a...

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...

Recent single crystal work on α-CoV2O6 has found a significant enhancement of the nuclear Bragg peaks on entering the low temperature antiferromagnetic states. This...

The NH4M(formate)3 (M = Mn, Fe, Co and Ni) series are the most promising members of a new family of multiferroics in which ferroelectric ordering is driven by hydrogen-bonding...

Materials with antiferromagnetic interactions between spins on a triangle lattice inherently exhibit large frustration between similar energy ground states giving rise to novel...

We propose to continuous our investigation of the magnetic diffraction pattern of the potential Kitaev spin liquid compound Li2RhO3. Moderate spin orbit coupling in the Rh4+ ion...

Unconventional superconductivity has recently been suggested in the new class of iron-based superconductors in which unusual gap symmetries have been observed together with...

The experimental realization of a S=1/2 kagome lattice has been one of the holy grail of frustrated magnetism because when all antiferromagnetic exchanges cannot be satisfied, a...

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

Ba2CuTeO6 is a newly discovered S=1/2 spin ladder system containing Cu2+ ladders. Our experiments indicate that this material is in very close proximity to the quantum critical...

We have recently discovered a new family of geometric frustrated magnets starting from the parent system, RbFe2F6, with crystallizes in the defect or β-pyrochlore structure...

One of the major themes in solid-state physics is the realisation of exotic types of relativistic electrons which travel at speeds much slower than the speed of light. These...

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