Spin orders in CaxMn2-xFeReO6 double perovskites
New manganese-based double perovskites Mn2-xCaxFeReO6 have been synthesised at high pressure. Mn2FeReO6 has spin-active cations at all sites; S = 5/2 Mn2+, S = 5/2 Fe3+ and S =... -
One- and multi-magnon excitations in a strong-leg quantum spin ladder
We propose to measure the one- and multi-magnon excitations in the first realization of a S=1/2 quantum spin ladder in the strong-leg regime. Our material, DIMPY, has very well... -
Investigation of the excitation spectrum in the 1D distorted diamond chain Az...
We propose to investigate the excitation spectrum of azurite in both zero field and applied fields up to 7T. Using inelastic neutrons on OSIRIS we hope to clearly resolve the... -
Quantum critical dynamics in the purely dipolar antiferromagnet LiErF4
LiErF4 is an example of an XY dipolar coupled antiferromagnet with planar anisotropy. As such it exhibits a quantum phase transition (QPT) in a small field of 4kOe, which is of... -
Field Induced Magnetic Phase Transition close to Ferromagnetic QCP's
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... -
Unique disorder in the ammonia hydrates at high pressure
The ammonia hydrates are important systems for the understanding of the hydrogen bond and for models of the outer solar system. This proposal is for beamtime to explore the... -
Contributions of ¿NH3+ torsions to phase transitions of glycine
It is proposed to investigate the torsional dynamics of the ¿NH3+ group of glycine-d2 in its three polymorphic forms using quasielastic neutron scattering (QENS). This study is... -
Magnetic energy levels of the tridiminished-icosahedron magnetic molecule {Fe9}
We propose to conduct inelastic neutron scattering measurements on a deuterated polycrystalline sample of the {Fe9} molecule [(Fe9-3-O)4 (O3PPh)3(O2CCMe3)13] to... -
Magnetic Excitations in Magnetic Molecule {Mo214V30}
We propose to conduct inelastic neutron scattering (INS) measurements on deuterated polycrystalline samples of the magnetic molecule {Mo214V30}, to determine the low-lying... -
Quantum Criticality in YFe2Al10
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... -
Spin waves in ferromagnetic YbNiSn
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...
