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

Justification: We'd like to apply for three days Director’s Discretionary time on WISH to continue the experiment on measures of quantum entanglement in a model 1D magnet. This...

YbNiSn is an Ising ferromagnet with non-colinear spins that undergoes a first order magnetic transition in low magnetic field (0.9 T). The transition is associated with strong...

The debate whether interband or intraband scattering is crucial for Fe-based superconductors is not settled down yet. Investigation a system with completely missing electron...

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...

Mirabilite (Na2SO4.10H2O) is relevant to many areas of geology, planetary science, and even the construction industry. It occurs naturally in evaporite deposits, and even as...

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

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...

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...

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 experimental realization of a Heisenberg-Kitaev model on the honeycomb lattice has been a major topic in a condensed matter physics, because the model predict a novel...

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,...

Na2Ti2Sb2O has a CDW transition around 120 K . It has a tetragonal structure with alternate layers of Ti2Sb2O2- and Na+ double layer. Interestingly, the Ba1-xNaxTi2Sb2O system...

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...

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...

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

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 manipulation of magnetic properties electronically is of great importance in modern computing. Current technology uses electric currents which draws a relatively large...

Both a natural mineral and quantum magnet, azurite is a candidate model of the so-called Distorted Diamond Chain system. Such a system should theoretically exhibit spin-1/3...

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...
