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... -
pressure induced para-antiferromagnetic switching in the multiferroic BiFeO3 ...
We have shown using previous experiments that moderate hydrostatic pressures can be used to switch phase from tetragonal to rhombohedral in the material BiFeO3 - PbTiO3 at room... -
Network compression and pressure-induced amorphisation in Zn(CN)2
Zn(CN)2 is an important material because it shows isotropic NTE over a large temperature range and to an extent more than double that of ZrW2O8. This unusual behaviour... -
Phase Behaviour in Pyrazine and Tetramethylpyrazine.
Pyrazine-I is stable < 302 K, phase II exists from 302-310 K, and phase III from 310-324 K. The known phase-I forms an ordered structure. It is thought that structures of...
