We have recently carried out an inelastic neutron scattering experiment at LET in order to investigate the excitations in the quantum spin ice Yb2Ti2O7. The single crystal...

Many novel electronic ground states form in close proximity to quantum critical points (QCPs), that is, the point where a continuous phase transition occurs at zero temperature....

KFe0.8Ag1.2Te2 is made of 2x2 squares of Fe atoms, upon lowering temperature the system spontaneously undergoes a transition that breaks the fourfold rotational symmetry. A...

Solar cells based on a layer of halide perovskite have recently seen rapid increases in efficiency, with certified values in excess of 20%. The prototypical material of this...

NdMnO3 exhibits A-type antiferromagnetism with TN =73 K. At 15 K, Nd sublattice orders with a (0, -Fy, 0) type ferromagnetic arrangement. Mn spin reorientation from (Ax, Fy, 0)...

Mn2Au has garnered a lot of interest as a promising material for the new field of antiferromagnetic spintronics. The symmetry of the crystal and magnetic order, already...

In a number of recent experiments on the pure CeB6 compound, we have revealed strong quasielastic inten-sity in the normal (paramagnetic) state with a rich momentum-space...

SrCu$_2$(BO$_3$)$_2$ (SCBO) is a very much studied quantum magnet that is most well known for its ground state of coupled singlets and multiple magnetization plateaux. Recently,...

Topological materials get extensive attention in last three decades. HgCr2Se4 is one of those materials being a Weyl semimetal which is induced by time-reversal symmetry...

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...

This proposal is part of our research programme to explore the spin dynamics of strongly-frustrated quantum antiferromagnets. A canonical model system is the spin-1/2 triangular...

The bilayer ruthenate Sr3Ru2O7 is the first material found to have a quantum critical end-point and is believed to display ¿nematic electronic order¿. We have previously studied...

The recently discovered quasi-one-dimensional (Q1D) superconductor A2Cr3As3 (A=K, Rb, and Cs with TC ≈ 6.1 K, 4.8 K, and 2.2 K, respectively) has intrigued intensive...

PbCuTe2O6 consists of a 3-dimensional arrangement of spin-1/2 Cu ions. There are 3 potentially strong interactions, the first neighbor interaction couples the magnetic ions into...

High pressure is a powerful thermodynamic tool, like temperature, to vary the properties and structure of materials. X-ray and neutron diffraction can be used to measure certain...

Mn12, with an anisotropy barrier close to 65 K, has been for 20 years a prototype nanomagnet, but in spite of a number of investigations the actual link between the value of the...

bismuth ferrite (BFO) remains the most studied multiferroic as a result of room temperature electric and magnetic ordering. However, real world applications are limited due to...
