Following recent experiments in which the shallow donor muon states in semiconductors are found to have significant electron polarisation at low temperatures and high fields, we...

A new family of FeAs superconductors have very recently (Autumn 2008) been discovered in which, rather than alternating rare earth oxide layers with FeAs layers (as for the new...

In centrosymmetric heavy-fermion (HF) superconductors Cooper pairs have either singlet or triplet symmetry. Recently a handful of non-centrosymmetric Ce-based HF compounds have...

By the virtue of having an entangled ground state the Heisenberg spin ½ chain systems provide a suitable perform to test multi-qubit quantum information protocols. There have...

NaTiO2 has been predicted to have a variety of unusual magnetic states, depending sensitively on the details of the crystal structure and interaction strength between the...

There is a lot of interest in Li based oxides that show potential to be used within cathode materials in batteries. However, in certain oxides, the addition of magnetic ions can...

Ho2-xYxSn2O7 is characterized by degenerate magnetic ground-states, which involve the magnetic structure for x->0 (Spin-Ice phase) and the two-fold degeneracy of the...

The two main pillars of the current research in molecular magnetism are the possibilities of exploiting molecules as classical bits in high-density magnetic memories or as...

lambda-(BETS)2GaCl4 is a non-magnetic anion-based organic superconductor SC attracting interest since its Fe analog becomes superconductor by applying 33 T. Both have similar Tc...

We propose to use inelastic neutron scattering to search for the existence of spin fluctuations in two iron phosphide superconductors, (La,Ca)FePO and Sr2ScFePO3. The objective...

Topological state of matter remains one of the central topics in condensed matter physics since decades ago. Take graphene as an example, the electron bands are linear and...

NaxC60 and LixC60 are wide theoretically studied systems for hydrogen storage. We recently investigated the hydrogen absorption/desorption of Na10C60 and we found that up to 3.5...

In physics, frustration describes a situation where a system is unable to satisfy all of its internal interactions because of the geometry of its atomic structure. The most...

Noncentrosymmetric superconductors have been identified as good candidates for unconventional superconductivity. In particular, there is the possibility of Cooper pairs with...

The recently superconductivity in a quasi-one-dimensional (Q1D) crystal structure, A2Cr3As3 (R=K, Rb and Cs), have been intensively investigated both experimentally and...

We have recently prepared mesoporous forms of various metals oxides. In some cases the imposition of a mesostructure changes other properties of the material significantly. One...

This is an extention of the previous proposal (RB920385), which was awarded 7 days.The experiment has not been performed yet (scheduled in November), but we forsee...

The present proposal is part of a larger EPSRC project advancing the vibrational spectroscopy of silicate glasses. The project involves the techniques of IR and Raman...

To our knowledge, the length of the U¿H single bond has never been accurately measured, at least not in a molecular compound by single-crystal neutron diffraction. We currently...

Ca3CoMnO6 has alternating ions in ferromagnetic Ising chains that are antiferromagnetically coupled on a triangular lattice and realizes an important model in frustrated...
