Some Ferroic Perovskite Solid Solutions
We are examining various perovskite solid solutions based on NaNbO3 or BiFeO3 that havepromising ferroelectric or multiferroic properties. All of these solid solutions show... -
Magnetic Structures of the RMnSbO (R = La, Nd) Oxy-Antimonides
The aim of the proposed experiment is to determine the temperature dependence of the ordered magnetic structures of LaMnSbO and NdMnSbO. These oxy-antimonides are related to the... -
Local Structure of TiNiSn-based thermoelectrics
We propose to study the local structure in two series of promising thermoelectric materials: Ti1-xZrxNiSn and TiNi1+ySn. Diffraction experiments on Ti1-xZrxNiSn reveal multiple... -
Structural Phase Diagram of the new Multiferroic Hexagonal YbFeO3
This experiment aims to map out the structural phase diagram of the new multiferroic compound hexagonal-YbFeO3 as a function of temperature, both above and below room... -
Investigation of Atomic Disorder Effects in Ti1-xZrxNiSn
We propose to investigate the arrangement of Ti, Zr, Ni and Sn over the 4 available atomic sites in the half-Heusler structure for the title series. This will help rationalise... -
Local structural effects in doped NaNbO3 ferroelectrics
Derivatives of the perovskite NaNbO3 are currently being studied as benign replacements for piezoelectric Pb(Zr,Ti)O3. In order to understand the structure-composition-property... -
Cation Ordering in Thermoelectric half-Heusler Materials
The main aim of the proposed experiment is to probe the cation distributions in a series of half-Heusler A(MZ) intermetallic phases that are considered for use in thermoelectric...
