In this work, we will examine the Li distribution in cubic and tetragonal La3Zr2Li7O12, tetragonal LaSr2Sb2Li7O12, as well as the variation in the distribution with temperature.... -
Structural phase diagram of rare earth substituted multiferroic BiFeO3
BiFeO3 is one of the most widely studied multiferroics (ferroelectric TC ~ 830°C, and antiferromagnetic TN ~ 370°C). Rare earth doping has been shown to be a suitable method of... -
Structural change investigation of CeNbO4 while dissociating H2O at high temp...
One potential solution to reduce the greenhouse gas emission is the generation of fuels through thermochemical dissociation of CO2 and H2O. Previous studies have shown that... -
Structural Studies of BiFeO3-KNbO3 Solid Solution
Both BiFeO3 and KNbO3 are technologically important materials. BiFeO3 exhibs room temperature magnetic and ferroelectric ordering whilst KNbO3 is a lead free ferroelectric.... -
The high temperature phases of multiferroic YMnO3
Hexagonal YMnO3 is a well-studied, but poorly understood, multiferroic material, which adopts the 'geometric' mechanism of ferroelectric distortion, rather than the more normal... -
Nuclear Structures of Lithium Substituted Layered Transition Metal Oxide Cath...
Novel cathode materials for rechargeable batteries have been under intense investigation since high cost and toxicity of current Li-ion batteries. We propose to study the... -
Structural Studies of Li(ND3)n11BD4
On exposure to ammonia, Li(11)BD4 forms the ammoniate Li(11)BD4(ND3)n. Our recent experiment (RB820252) has shown that there are four distinct crystalline phases in the... -
Low-Temperature Structural Phase Transitions in GeV4S8
