Excitations of a solitonic lattice in the multiferroic material TbFeO3
The multiferroic system TbFeO3 undergoes magnetic transitions at 8.5 and 3 K, and with further modification in applied fields leading to a complex H-T phase diagram. At a... -
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... -
Determining the Hamiltonian of a New Quantum Spin Ice Material
Pr2Hf2O7 is a potential quantum spin ice compound. Compared to the classical spin ice ions Ho3+ and Dy3+, Pr3+ has weaker Ising anisotropy and significant XY terms leading to... -
The role of zero-point fluctuations in a quantum-disordered spin-dimer compound
Recently a great deal of theoretical and experimental interest has been directed at a class of magnetic materials which undergo phase transitions at zero temperature. These... -
Magnetic excitations in Strontium Erbium Oxide
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... -
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... -

We propose to conduct inelastic neutron scattering (INS) measurements on deuterated polycrystalline samples of the magnetic molecule {Mo214V30}, to determine the low-lying... -
Neutron Diffraction study of Highly Frustrated SrEr2O4
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... -
Magnetic excitations in multiferroic hybrid perovskites
The novel electric, magnetic and multiferroic properties of the metal formate perovskites have resulted in substantial scientific attention over the past fifteen years. Their... -
