Local structure and vibrational properties of strontium vanadium oxyhydrides
This proposal concerns the investigation of the local structure and vibrational dynamics of hydride-ions in a series of strontium vanadium oxide-hydrides by inelastic neutron scattering. The series of samples are featured by different dimensionalities in the hydride-ion sublattice, ranging from ordered rows, to planes, and finally to a disordered 3D anion lattice. The aim of this study is thus to investigate how the local coordination and vibrational dynamics of the hydride-ions change as a function of dimensionality, and possibly how it is influenced by the magnetism. Besides, being of considerable fundamental interest, understanding the nature of local structure and dynamics of the hydride ions in these materials is of great importance for developing efficient synthesis routes that allow the development of new oxyhydrides with tailored properties.
