In orbitally degenerated triangular system it is predicted that orbital ordering and associated local magnetic trimerization to remove frustration. In BaV10O15 lattice...

Neutron spectroscopy is applied to study bones exposed to anaerobic burning or fossilisation. The results thus obtained will complement previous data gathered by the team on...

High entropy alloys are receiving significant attention worldwide as a new class of materials that offer unique and attractive properties. However, controversy exists over their...

Lead based oxides are wildly used in material science in order to obtain non-centrosymmetric structures that eventually lead to polar or piezoelectric distortion, which coupled...

The spin-chain systems with general formula A¿3ABO6, crystallizing in the K4CdCl6 type structure has attracted a lot attention in recent years due to geometrical frustration...

Our picture of the structure of organic solids is derived almost exclusively on ?conventional? crystal structures based on Bragg scattering. Though it is hard to overstate the...

We have observed an anomalous monotonically increasing longitudinal field relaxation rate in LiY_(1-x)Ho_xF_4 for applied fields above 1000 G (along the c-axis) and at a...

Incommensurate magnetic phases generated by frustrated magnetic exchange interactions can stabilise novel induced magnetoelectrics. We have recently found that the...

Colossal magnetoresistance (CMR) is observed in the oxypnictide NdMnAsO1-xFx (x = 0 - 0.085) at low temperature. The CMR in NdMnAsO1-xFx arises due to competition between a...

The modified pyrochlores AM2+M3+F6 (A alkali metal ion, M transition metal ion) are a class of highly frustrated materials that have a randomness associated with the positions...

A recent exciting development in magnetic materials was the discovery of a new iron oxide, Fe4O5, using high temperature and high pressure. A very recent structural study has...

The interface between nickel bismuth layers is widely reported to be superconducting and due to the proximity of ferromagnetic and high spin-orbit-coupling layers, it is...

We propose elastic neutron powder diffraction experiments on perovskite antimonates (Ba,K)SbO3. Main-group oxide perovskites have attracted intense research interest due to...

Dy3Mg2Sb3O14 forms a layered structure with magnetic Dy3+ ions forming sheets of corner sharing triangles, called a Kagome lattice. The Ising magnetic moments are constrained to...

The National Physical Laboratory (NPL) and the WISH instrument team has worked together to enable simultaneous real-time high resolution (powder and single crystal) neutron...

The recently reported double perovskite analogue imidazolium potassium iron(III) cyanide is noteworthy for two reasons. First, the order-disorder phase transitions, in which the...

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...

The exotic physics of low-dimensional quantum magnets has recently been highlighted by the award of a Nobel Prize to Duncan Haldane. We have identified the molecular framework...

The search for new porous materials is increasingly be driven by socio-economic pressure to diversify our energy supply and minimize environmental impact. Carbon-based...

The metal-organic framework perovskite analogue guanadinium copper(II) formate has achieved considerable recent attention for its multiferroic properties and consequent...
