Chasing the symmetry of the BiFeO3 γ-phase in the isostructural A- and B...
BiFeO3 is by far the most widely studied multiferroic material and yet many mysteries remain in the phase diagram. One mystery is the crystal structure of the high T gamma... -
Electron localisation in vanadium hollandites
Hollandites (AxM8O16, where A is a large cation and M is a transition metal, here vanadium) have been studied for a wide range of properties, including electronic phenomena such... -
Crystal and Magnetic Structures of Multiferroic Ammonium Formates NH4M(HCO2)3...
The NH4M(formate)3 (M = Mn, Fe, Co and Ni) series are the most promising members of a new family of multiferroics in which ferroelectric ordering is driven by hydrogen-bonding... -
The Structure of Ca- and Yb-ammonia Solutions: Polarons, Bipolarons and Elect...
In this experiment we propose to perform diffraction on isotopically substituted samples of Ca/Yb:ND/H3 and Ca/Yb:15ND3 at two concentrations (8 and 2 MPM) using the new NIMROD... -
Complexity in simplicity: disentangling Pb2+ disorder in PbS, PbSe and PbTe
We ask for 5 days on SXD to study the detailed crystal structures of PbS, PbSe and PbTe to resolve long-standing, topical controversies about the detailed behaviour of this...
