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 propose to use a pulsed magnet system tried and tested at several neutron and synchrotron facilities in conjunction with the new high flux diffractometer WISH to perform the...

We propose a study of the low temperature magnetic structure of vanadium dioxide (VO2) compounds using long-wavelength neutron diffraction measurements. This study directly...

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...

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...

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...

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

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

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...

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

One-dimensional magnetic materials have been widely studied due to their often remarkable ground states and excitations. Recent study of the triclinic form of CoV2O6 brannerite...

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 layered ternary oxide system has been intensively studied in the past as it exhibits various remarkable properties, such as its electrochemical behavior as positive...

YbAl3C3 exhibits a spin gap formation due to spin dimer ground state below 10 K. In zero-field the ground state is paramagnetic and no sign of long range magnetic ordering down...
