Recent theoretical analyses of quantum spin ice has revealed the present of a novel magnetic excitation whose quantum properties are analogous to photons. This mode is a...

One-dimensional (1D) or two-dimensional (2D) topologies between magnetic ions generally favour strong magnetic anisotropy and offer exotic fundamental states and other phenomena...

2D honeycomb iridates recently emerged as a possible platform for new class of spin liquid, the Kitaev spin liquid. The candidate materials A2IrO3 (A = Li, Na) in fact undergo...

This proposal is part of our research programme to explore novel phases stabilized by the combined effect of spin-orbit interaction and electron correlations. Here we aim to...

Quantum spin liquids are exotic states of magnetic matter in which conventional magnetic ordering is suppressed. Magnetic analogues of ice are good candidates to observe this...

Hertbertsmithite ZnCu3(OH)6Cl2 is a model S =1/2 kagome antiferromagnet, received much attention last years. From recent studies a sign of a nearby quantum phase transition...

Recent single crystal work on α-CoV2O6 has found a significant enhancement of the nuclear Bragg peaks on entering the low temperature antiferromagnetic states. This...

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...

We propose to continue our investigation on LET of the Shastry-Sutherland compound SrCu2(BO3)2. The first part of the experiment aims to establish the Q-dependence, which will...

The control of physical properties through cation ordering in perovskites often gives rise to unexpected and desirable functionality. Of particular interest in the preparation...

Quantum spin liquids (QSLs) are new and exotic states of matter characterised by fractionalised excitations and macroscopically degenerate ground states. The S=1/2 kagome...

We propose neutron scattering measurements of the atomic momentum distribution and the Bose-Einstein condensate (BEC) fraction, n0(T) of liquid 4He confined in Vycor. Liquid 4He...

There are no magneto-structural correlations for clusters containing transition metal ions with non-zero orbital angular momentum in the ground state. Octahedrally coordinated...

In the metal-organic perovskite copper guanidinium formate, correlated Jahn-Teller distortion gives rise to a 1D magnetic structure made up of Heisenberg antiferromagnetic...

Magnetically modulated structures have been predicted to form close to quantum critical points in a number of recent theories, although there are no experimental examples of...

New layered perovskite compounds LaBaFeMnO5 and LaBaFeMnO6 were recently synthesized. They may be useful for future oxygen storage applications. Fe-Mössbauer spectroscopy has...

The physisorptive capability of graphite-based nanomaterials for hydrogen is strongly dependent on their surface areas and nanomorphologies. We have made electrospun graphite...

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...

Ionic liquids are of interest to chemistry and material sciences because of their designer properties. Protonated ionic liquids are excellent proton carriers in fuel cell...

In Ce-based heavy fermion materials, there is competition between the interactions which lead to a magnetically ordered arrangement of the Ce magnetic moments, and the...
