Transition metal pyrovanadate M2V2O7 (M = Ni, Co, Mn) exist with a great variety of crystal structures, which are reflected in the richness of their physical properties....

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...

We have synthesized the polycrystalline R2BaCuO5 (R = Dy & Ho) and studied its physical properties. Indeed, both the studied compounds exhibit the polarization below rare...

Magnetic and orbital ordering in the manganese based perovskites has been of huge interest in solid-state physics since the 1950's. More recently, the family of AA′3Mn4O12...

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...

We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the...

Purely ferromagnetic (FM) oxides are uncommon but we recently reported FM behaviour in a mineral induced by quite small magnetic fields. This ability relates to the presence of...

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 experiments on single crystals, 3R-AgFeO2 and 2H-AgFeO2 on WISH. Recently, we have studied magnetic orderings and ferroelectricity of...

This study is designed to identify relationships between structure and magnetic properties characteristic of coordination polymers (CPs), specifically in the model system...

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...

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....

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...

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...

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...
