The magnon density of states in NiPS3
NiPS3 is an example of a low-dimensional magnetic system. It is potentially a 'model' magnet, meaning that it might be a good material to search for new phenomena that have been... -
Crystal-chemical environment of lithium atoms in battery anode materials
We want to investigate and Rietveld-refine the crystal structures of a number of lithium titanates and niobates of interest as battery anode materials. Some of these phases have... -
Unpicking the signal of partial order from thermal motion in diffuse scatteri...
Orientationally-disordered water molecules in ice adopt a degree of partial order upon cooling, a process that is halted by kinetics at ~100 K in pure ice and ~60 K in KOH-doped... -
Deuteration-induced phase transition in a multiferroic framework material
The hybrid organic-inorganic perovskites are of great interest as functional materials, because they combine the well-established perovskite topology with new physics and... -
