Materials with large caloric effects offer the opportunity to replace current refrigeration technologies that require the compression of hazardous gases. Whilst magnetocaloric...

The compounds we want to study belong to the well-known tetragonal RM2X2 family (R: rare earth, M: d element, X: Ge, Si). In EuCu2(SixGe1-x)2, the Eu valence changes, as a...

The recently discovered iron based superconductors have transition temperatures second only to the cuprates. The majority of these compounds display superconductivity after...

Sustainable energy-conversion technologies are important for ensuring our energy supply against declining fossil fuel reserves. Thermoelectric materials offer great potential...

One fundamental issue in the iron-based superconductors is whether the conventional local moment Heisenberg model is sufficient to describe magnetism in these materials, or...

The Dzyaloshinskii-Moriya interaction is thought to be responsible for the stabilization of weak ferromagnetism or magnetic spiral states in a number of diverse systems. An...

We propose to use MARI to (1) compare the properties of the crystal field (CF) scheme between Yb2GaSbO7 (YGSO) and its parent compound Yb2Ti2O7, in hopes of elucidating the...

The A2B2O7 pyrochlore family, where A is a rare earth ion and B=Ti, Sn, is one of the most prolific series of compounds presenting magnetic frustration. The geometric Fd-3m...

We propose to use MERLIN to measure INS from commercial zeolite catalyst samples extracted from a reactor in which they have been exposed to dimethylether for different lengths...

The rare-earth compound KYbSe2 provides a new chance for the study of frustrated magnets with strong SOC. It resembles YbMgGaO4 in many ways. Our susceptibility and specific...

We propose an investigation of the spin-waves in the recently discovered room-temperature skyrmion material Co8Zn8Mn4. The ground state of Co8Zn8Mn4 is a very long wavelength...

Spin excitations is correlated with superconductivity in high Tc superconductors. The spin excitations in La2-xSrxCuO4 superconductors become weaker in overdoped region and...

As part of a UK Catalysis Hub initiative in Catalyst Design involving a team of academic and industrial researchers, the methanol-to-gasoline reaction over zeolite catalysts is...

Recent unpublished data collected at MAPS by our group revealed that the spin wave dispersion of the Ba(122) parent differ significantly from Ca(122). In Ba(122) there is a...

This proposal requests 2 days on MERLIN to measure the INS spectrum of the novel perovskite type oxyhydride BaTiO3-xHx (x = 0.4). Prevision INS measurements, on TOSCA, have...

Ammonia borane (AB) is one of the most promising hydrogen storage materials. There has recently been work on a more mobile phase of AB (denoted AB*) which is formed (via the...

In a magnetic Weyl semimetal (WSM) with broken time-reversal symmetry, large intrinsic anomalous Hall effect is expected if the Weyl nodes are close to Fermi energy, which...

For the first time, the research team aim to use INS to characterise a series of new high specification methane reforming catalysts. The enhanced performance of these catalysts...

Mn3Sn has very complex magnetic ordered phase, a clear magnetic phase transition happens at T=~280K accompanied by the vanishing of AHE.For our Mn3Sn crystal grown by flux...

In contrast to the extensively verified Weyl semimetals with broken inversion symmetry, magnetic Weyl semimetals, which break time reversal symmetry, were only theoretically...
