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... -
High-pressure studies of inorganic azides
This proposal seeks to identify and structurally characterise the high-pressure phases of the azide salts of sodium, silver, lead, and the ammonium ion. Azides are examples of... -
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... -
Pressure and Temperature-Induced Phase Transformations in PbZrO3-BiFeO3 Ceramics
The proposed experiment involves identification of the phase boundaries and determination of the crystal structures of PbZrO3-BiFeO3 (PZ-BF) ceramics as a function of... -
A high-pressure study of monovalent bifluorides
This proposal seeks PEARL beam time to conduct the first high-pressure neutron diffraction study of the monovalent azides XDF2, where X = Na, ND4, Cs and Tl. In so doing, we...
