Local magnetic interactions in lanthanide compounds have recently been shown to tune their entropically driven magnetocaloric effect (MCE), useful for magnetic coolants. In this... -
Neutron analysis of the structure of SrAl2O4 from 300 to 1273 K.
SrAl2O4 is a stuffed tridymite that has attracted a good deal of interest, since doping with Eu2+ leads to a material with elastic-luminescent response. The structure and phase... -
Investigation of the phase diagram of Ba1-xNaxTi2Sb2O (WISH portion)
We propose using WISH and HRPD to examine the structure of the Ba1-xNaxTi2Sb2O phase diagram as a function of temperature. The primary goals are the determination of the... -
Magnetism and electronic structure of 3d 5d double perovskites
Emerging technologies require increasingly unusual functional materials and so understanding the origins of complex magnetic and electronic behaviour, and how these can be... -
Investigations of some ruthenates with extended superexchange pathways
The superexchange interaction - in which the intervening oxygen mediates magnetism between two partially filled d shells- is well described by the semi-empirical... -
