Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...

We propose to measure the neutron diffraction pattern of a single crystal sample of SrEr2O4, using the WISH diffractometer. As the magnetic Er ions in this compound are linked...

We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the...

Recent experiences applying INS to examine a series of nickel-based methane reforming catalysts have enabled a generic experimental methodology to be developed. In collaboration...

The triangular Heisenberg antiferromagnet is the classic example of the frustrated magnet, here the ground state forms a non-collinear 120° structure. A number of different...

Cu2OSeO3 belongs to a family of magnetic crystals that displays unique properties of a whirlpool like vortex of magnetic moments (skyrmions) in a small range of temperature and...

The heavy fermion system CeCu6-xAux is arguably the most important (and studied) heavy fermion series which exhibits a quantum critical point. In recent years several new...

A new rare-earth triangular quantum spin liquid (QSL) candidate, YbMgGaO4, has an odd number of electrons per unit cell and spin-orbit entangled effective spin-1/2 (Yb3+)....

SrCo2V2O8 is a quasi-1D, S-1/2 antiferromagnet with XXZ anisotropy. Weak interchains coupling result in long-range magnetic order at a finite temperature TN. A spinon continuum...

Evidence of long-range order has been observed in the diffuse neutron scattering data for a single crystal of HoTbTi2O7.A spin ice like pattern and pinch points coexist with the...

The growth in both global demand for energy and fossil-fuel related environmental issues drive research on alternative fuel sources. Solid oxide fuel cells, which can operate on...

The recently synthesised triangular-lattice rare-earth magnet KErSe2 crystallizes in the similar strucutre as the new quantum spin liquid candidate YbMgGaO4 but with less stie...

SrCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions that are coupled into network of isolated triangles,a highly frustrated hyperkagome lattice consisting of...
