The layered NaMnO2 is challenging as it is an experimental realization of a two-dimensional spin-2, spatially anisotropic triangular lattice, where the interplay of temperature...

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

The family of guanadinium metal formates (M=Mn, Fe, Co, Ni, Cu) are isostructural with the perovskites and are therefore of interest for potential applications: in particular,...

TbMnO3 attracts special attention due to its large magnetoelectric coupling, polarization flop and ferro-paramagnetic phase transition, both induced by magnetic field. Despite...

The coupling between magnetic and electric degrees of freedom, in a single phase compound has been of intense research in recent literature, as the outcome would yield novel...

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...

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...

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 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...

The crystal structure of PrFe2Al8 consists of a network of Al which forms quasi cage-like structure where the Pr and the Fe form chains of atoms along the c-axis. We propose...

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 spin Jahn-Teller effect stabilises 3D magnetic order in an otherwise frustrated system via magnetoelastic coupling, spontaneously at the magnetic phase transition. Examples...

This proposal requests time to investigate the influence of an applied magnetic field on the oxyselenide Pr2O2Fe2OSe2. A metamagnetic transition involving ordering of Pr3+...

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...

In recent years, there has been a large research interest in noncentrosymmetric systems in part due to the exotic physics these systems display. Examples of chiral magnets...

The new compound Bi2CoTiO6 is synthesized using high pressure - high temperature techniques. Its properties were characterized by X-ray diffraction, magnetic measurements, and...

We propose to test new apparatus for the magnetic neutron diffraction under uniaxial pressure on WISH diffractometer. The main feature of our apparatus is that the sample is not...

Encouraged by many unconventional magnetic properties in the magnetically frustrated spin-chain compounds of the type A3MM'O6, we have recently synthesized a new member...
