Two-Dimensional Incommensurate Modulation in Melilite
We have prepared large single crystals of the melilite electroltyes Ln1+xCaxGa3O7+d; (Ln = La and Nd; x = 0 and 0.5) using a floating zone mirror furnace. We have characterised... -
INS Analysis of Kaolinite and its Dehydroxylation Products
This application for beam time on TOSCA is a crucial component of a study into the dynamics, structure and reactivity of kaolinite and its dehydroxylation products.... -
Soft Modes in the Ferroelectric Semiconductor SbSI
Antimony sulfo-iodide (SbSI) exhibits strongly-coupled photoconductive, semiconducting, and ferroelectric properties. Until the discovery of the lead-oxide ferroelectric relaxor... -
Magnetic excitations in the S=1/2 ferromagnetic semiconductor Lu2V2O7
Lu2V2O7 is a rare example of an S=1/2 pyrochlore. The fact that it is a ferromagnet with Tc=70 K belies the fact that it has some truly remarkable properties. These include the... -
Neutron scattering and muSR studies of magnetic phenomena in YFe2Al10: case s...
In strongly correlated electron systems, the proximity to magnetic ordering has been of special interest. Magnetism in this class of systems is often suppressed by the Kondo... -
Phonon Anomalies in YMnO3 at High Temperature
The reported structural phase transition in YMnO3 from P63cm to P63/mmc space group occurs at 1258 ±14 K. For low temperature phase (space group P63cm) the phonon modes are... -
