YbNiSn is a Yb analogue of ferromagnetic superconductors URhGe and UCoGe. All materials share the same crystal structure, have similar Curie temperatures and a similar...

The recent discovery of skyrmions and skyrmion lattices in materials with no inversion symmetry and their corresponding potential applications of Skyrmions in magnetic...

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...

The spinel GeCo2O4 is a promising compound to establish the consequences of geometrical frustration, as the magnetic Co2+ ions are on a network of corner-sharing tetrahedra...

Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the...

This proposal is part of our research programme to explore the interplay of thermal and quantum fluctuations near zero-temperature quantum phase transitions. Here we apply for a...

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...

As far as we know there is no single crystal neutron study on ErPr_2Si_2 yet, mainly due to fabrication difficulties. We have grown large (diameter: 6 mm; length: 8 mm) single...

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...

Interesting behaviour in Heisenberg spin systems originates from networks of triangles or tetrahedra, where spins interact via antiferromagnetic interactions. In 3D there are...

The experimental realization of a Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model uniquely provides exactly...

Uniaxial stress has been used to study the Fe-based superconductors with spectacular results. Both the transport properties and the low-energy magnetic excitations have been...

Given the challenges in providing efficient and non-harmful refrigeration, it is timely to study barocaloric systems, which offer cooling power via the application of pressure,...

Our previous neutron diffraction on C14 Laves phase compounds Nb1-xFe2+x revealed thata spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...

CeRu2Al10 belongs to the CeT2Al10 family (T: Ru, Os, Fe), which exhibits Kondo-insulator behavior and high magnetic ordering temperature (TN=27K), with an unusual competition of...

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....

UPd3 exhibits four antiferroquadrupolar (AFQ) ordered phases below T0=7.6K. We have determined their order parameters using resonant x-ray diffraction. UPd3 has the dhcp crystal...

We propose to conduct a high resolution neutron inelastic scattering study of the ferromagnetic superconductor UCoGe. Initial polarised results obtained at 4F1 (Saclay) are...

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

CaFe2O4 shows an interplay between magnetic structures termed the A and B phases. In this proposal, we request time to measure the spin wave dispersion using MERLIN. Previous...
