We propose to use WISH to characterise magnetic order of a new quantum (S=1/2) geometrically frustrated material based on the mineral averievite, Cu_5(VO_4)_2O_2CsCl. This...

Manganites oxides are of great interest in material sciences for the variety of physical properties they exhibit in connexion with possible long range spin, charge and orbital...

When isolated spin clusters are weakly coupled to each other, zero-dimensional quantum and three-dimensional collective magnetism concomitantly occur. This is envisioned in the...

In this proposal, we would like to propose to perform neutron diffraction experiments on the powder samples of the frustrated antiferromagnets AFeO2 (A=Cu and Ag) using WISH. In...

Exotic electronic states are of great interest to fundamental science, such as the quantum spin-liquids (QSLs) which were theorised to behave like a sea of resonating spin...

Three new doubly ordered perovskites NaYMWO6 (M=Mn, Co & Ni) have been synthesized by high pressure and high temperature. Analysis of room temperature laboratory X-ray...

Dirac fermions with linear energy dispersion with momentum space have been of current interest for spintronic applications because a variety of quantum transport phenomena...

We propose to perform neutron diffraction experiments under high-pressure on a frustrated antiferromagnet CuFeO2 using WISH in combination with hybrid-anvil-type high-pressure...

Systems of the CsCoX3 family form antiferromagnetic chains along the c-axis, and are arranged in a frustrated triangular arrangement in the ab-plane. Below 30K, both systems...

The layered compound Na2Co2TeO6 is a model honeycomb compound having a zigzag antiferromagnetic (AFM) ground state. Na2Co2TeO6 poses a rich magnetic phase diagram in the H-T...

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...

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 electronic dispersion of "Dirac" materials such as graphene and topological insulators is linear, resulting in a variety of peculiar electronic properties. In graphene and...

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...

Ferroelectricity induced by magnetic ordering with certain type of magnetic structure has received much attention because it provides opportunity to manipulate magnetization by...

Test of the NIMS low temperature pressure cell on WISH.

This study is designed to identify relationships between structure and magnetic properties characteristic of coordination polymers (CPs). By determining the ground state 3D...

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

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...
