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...

We have discovered a novel type of quantum spin liquid in a hexagonal lattice of Ru5+ dimers in Ba3ZnRu2O9, where any traces of the Curie tail or glassy behavior have not been...

The formation of charge and spin density wave (CDW and SDW) states in metallic systems isdriven by Fermi surface instabilities that are often found to compete with...

We propose to study an effect of uniaxial pressure on a magnetic structure of triangular antiferromagnet PdCrO2. The experiment will mark a technical milestone in development of...

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...

FeSe is structurally the simplest iron-based superconductor but one of the most intriguing electronically, with extreme tunability in its electronic and superconducting...

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...

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...

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...

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...

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...

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

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...

Ba4Ru3O10 is a rather fascinating compound with quasi two dimensional crystal structure. Although the compound shows strong feature in the magnetization data at 105 K indicating...

Our aim is to study with high resolution neutron powder diffraction the two orthorhombic phases of Mn2TeO6 at RT, so as to understand the origin of the observed structural...

Research into the quadruple perovskite manganites has expanded, owing to recent discoveries of technologically relevant properties and entirely novel electronic states. Through...
