The proposal is to measure the low-energy spin dynamics of the ferromagnetic superconductor UGe2 at the pressure which maximizes superconducting transition temperature and at...

The experimental identification of quantum spin liquids (QSL) in real materials has been one of the challenging and fundamental goals in condensed matter physics. The newly...

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...

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 plan to use...

This proposal addresses the formation of a metamagnetic phase transition in PrPtAl. PrPtAl exhibits induced moment magnetism where singlet-mixing is stabilised by inter-site...

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

A strong Q-dependence of the magnetic response at characteristic energy of EK~kBTK (TK is a Kondo temperature) has been observed in recent inelastic neutron scattering studies...

Pyrochlore compounds are considered to have an ideal crystal structure for 3D geometrical frustration, resulting in novel ground states. Spin ice, is one of the most striking...

We plan to study the effect of magnetic field on the spin excitations in the newly discovered quantum spin liquid Na2BaCo(PO4)2. Our preliminary inelastic neutron scattering...

LixCoO2 is used extensively in portable batteries in laptops and mobile phones, but the scarcity of Li means that alternative materials are required. Structurally related...

The inter-metallic B20 compound MnSi is of great interest as a magnetic model system exhibiting helical spin ordering and topologically non-trivial spin correlations. The...

Magnetically modulated structures have been predicted to form close to quantum critical points in a number of recent theories, although there are no experimental examples of...

The proposal requests time to measure the low-energy excitations in CaFe2O4 as a function of temperature. Previous experiments have observed a series of in-gap states at high...

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...

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...

Low-dimensional quantum spin systems with introduced disorder are a fascinating playground for investigations of the interplay between quantum effects, strong correlations and...

The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...
