Cation environments in lead-free glasses
BaO+ZnO containing glasses are being studied as an alternative to lead-based glasses because they exhibit excellent dielectric, thermal, optical and crystallisation properties.... -
Cation environment and the tellurite anomaly
We have recently shown that the anomalous behaviour of the Te-O coordination number, nTeO, for binary tellurite glasses is related to the presence of terminal Te=O bonds in... -
Cation substitution in synthetic meridianiite (MgSO4.11D2O): phase behaviour ...
MgSO4.11H2O (MS11) is the most highly hydrated phase in the binary MgSO4¿H2O system. Whilst lower hydrates in this system have end-member analogues containing alternative... -
Cation ordered transtion metal oxides
LaCa2Fe2GaO8 adopts a 3-layer cation-ordered structure. Magnetisation data collected from this phase exhibit two high-temperature anomalies consistent with the onset of... -
Cation substitution in synthetic meridianiite (MgSO4.11H2O): site distributio...
MgSO4.11H2O (MS11) is the most highly hydrated phase in the binary MgSO4¿H2O system. Whilst lower hydrates in this system have end-member analogues containing alternative... -
Cation site disorder in KTiOPO4 isostructures
KTiOPO4 (KTP) is a well known non-linear optical material. Its crystal structure has highly asymmetric Ti-O bonds, a rigid TiO6-PO4 lattice and K cations trapped in cages. The... -
Cation Ordering and Magnetic Properties of Layered Tellurides
We have prepared a new non-stoichiometric series Cr2-xInxGe2Te6. X-ray diffraction data can be indexed on the rhombohedral unit cell of the end-member (x=0) phase. This adopts a... -
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...
