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...

Our previous neutron scattering on C14 Laves phase compounds Nb1-yFe2+y revealed that a spin-density-wave (SDW) is masking an underlying ferromagnetic (FM) quantum critical...

We have recently discovered solitary magnons in the classical magnet CaFe2O4 below 3 meV. in this experiment we propose to extend this to higher energy transfers to track how...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. We have extensively studied the low temperature behaviour of this material This proposal asks for 3...

Arguably the most-famous quantum phase transition is the Bose-Einstein condensation (BEC) of magnons. It can be studied experimentally in gapped quantum paramagnets when an...

Quantum phase transitions, where correlation length and time scales diverge, are of broad interest to the condensed matter physics community. The new layered material YFe2Al10...

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...

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...

The Ising chain realises the fundamental paradigm of spin fractionalization, where locally flipping a spin creates two kinks (spinons) that can separate away at no energy cost,...

X-ray induced radiation damage drastically limits the structural information accessible in diffraction experiments from macromolecules at 3rd generation synchrotrons. Relatively...

ZnCr2Se4 is a magnetically frustrated spinel compound with an incommensurate ground state. At low temperatures it displays a spin spiral structure propagating along the (100)...

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...

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...

The Heusler alloys Ni-Mn-Ga are widely considered as a new generation of multifunctional smart materials due to the mutual interplay between structural and magnetic properties...

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...

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

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...

In our recent NRSE experiment on the quasi two-dimensional quantum spin liquid PHCC at TRISP at FRM-II, we have found a zero field splitting (ZFS) of the magnon line of about 50...

The spin Seebeck effect is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric energy generators. SSE...

During recent years, the study of T=0 quantum phase transitions (QPT), the emergent scaling properties and their profound influence on physical properties at T>0 has...
