Structural transformations in pure and Ba-doped PbSc$_{0.5}$Nb$_{0.5}$O$_3$ u...
Lead scandium niobate (PSN) belongs to the class of perovskite-type relaxor ferroelectrics, which are among the key functional materials. Due to their structural complexity, the... -
Structural study of high pressure phases of multiferroic BiFeO3
BiFeO3 is a rare example of multiferroic material with a simple perovskite-like structure, having extremely large magnetic ordering temperature (TN = 650 K) and Curie... -
The Pressure and Temperature Dependence of the Structure of Ammonium Triiodide
We have shown that the molecular ionic solids MI3 (M=Tl, Cs, Tl, NH4) undergo structural phase transitions below 3.4 GPa at RT to give the same new high pressure phase (HP) with... -
A high-pressure study of N,N'-dimethylurea
This proposal seeks to explore the high-pressure structural behaviour of N,N¿-dimethylurea. Two new high-pressure forms have been structurally characterised using x-ray methods,...
