The f-electron metal Yb2Pt2Pb is best thought of as a one dimensional (1D) quantum spin chain system, despite the fact that the magnetic moments are large and anisotropic with...

Nd2Zr2O7 is a new candidate for quantum spin ice proposed theoretically. It has a well-isolated dipolar-octupolar doublet with Ising anisotropy as the crystal field ground state...

Nature abhors disorder and degeneracy at low temperature. Designing materials that confront this requirement can therefore lead to new states in which the degeneracy is lifted....

The proposal is to measure the inelastic scattering from a single crystal of Åkermanite on cooling towards and through the incommensurate phase transition at 358 K. There are...

We recently observed a resonant spin excitation in Ba1-xKxFe2As2 (x=0.4), one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates...

Geometrically frustrated spin systems have been studied extensively for decades because of many intriguing phenomena, exemplified by the non-magnetic quantum disordered states....

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...

We have observed an interesting phenomenon of the destruction of long-range magnetic order in SrEr2O4 by a relatively modest applied magnetic field. For a field applied along...

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...

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 proposal requests time on OSIRIS to measure the low-energy magnetic fluctuations in CeRhSi3. This compound is a noncentrosymmetric superconductor under pressures of ~10...

Recently, new type of frustrated magnets, BaV10O15 and SrV10O15, were found to exhibit interesting phenomena due to mixed valence ions forming a modified triangular lattice....

Recent high resolution spectroscopy has found countable and discrete excitations in the two dimensional magnet CaFe2O4. This work aims to track these excitations to higher...

The organic-inorganic perovskites with chemical formula CH3NH3PbB(Br,Cl,I)3 have been implicated as being efficient photovoltaic materials. Theoretical calculations and...

In SrEr2O4 the magnetic Er ions are linked through a network of triangles and hexagons, where geometrical frustration can arise, provided that some exchange interactions are...

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+)....

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...

Ferromagnetism in URhGe is continuously suppressed with a magnetic field leading to a Quantum Critical Point (QCP) at around 12 T engulfed by a pocket of superconductivity. The...

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...
