A Total Scattering Study of Local Structure in BIMEVOXes
The BIMEVOXes are an important family of fast oxide ion conducting solids that exhibit very high conductivities at low and intermediate temperatures. A study of local ordering... -
Structure of SnO-P2O5 glasses doped with heavy metal oxides
The exchange of Pb by Sn in high-refractive index and low temperature process glasses is a common need in pollution control. Here it is planned to study the structure of binary... -
Phase Diagram of Ba1-xKxFe2As2
In the new class of iron pnictide superconductors, there is evidence of phase coexistence close to the phase boundary between the SDW and superconducting order produced by hole... -
Ground state selection in quantum spin ice pyrochlores
In condensed matter physics, the search for new exotic quantum ground states has become a central theme over the past few years. Among the 3D quantum spin liquid candidates, the... -
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... -
A quantitative understanding of magneto-electrical coupling in the multiferro...
The multiferroic (type II) compound, CoCr2O4 undergoes a spiral magnetic ordering and concomitant ferroelectric transition at the spiral ordering temperature (26.3 K). The... -
Structure-conductivity relationship in La2-xBaxNiO4+d
Unusual total conductivity behaviour at high Ba contents may be attributed to a change in conduction mechanism at high tempertaures, structure change or phase... -
Investigation of the relaxor-photoferroelectric Ba(Sn,Ti)O3 compounds using n...
The local structural distortions in BaTiO3-based solid solutions, where the Ti4+ site is substituted by isovalent Sn4+ cation Ba(Sn,Ti)O3, are characterized by no oxygen tilts... -
High field study of multipiezo Pb2MnO4
Manganese based oxides are of great interest for both spintronic and multiferroic applications.Pb2MnO4 crystallizes in the acentric but non-polar space group P-421c which allows... -
Doping Dependence of the Resonant Spin Excitation in Ba1-xKxFe2As2
We recently observed a resonant spin excitation in Ba0.6K0.4Fe2As2, one of the newly discovered iron arsenide superconductors with Tc=38K, on MERLIN. This demonstrates that the... -
Isotope dependence of the Néel Temperature in cuprates
The effect of isotope exchange on the Néel temperature in the cuprates was neer determined because it was impossible to perform relaible isotope exchanges in the parent... -
Inelastic neutron scattering and musr studies of the high-distorted double pe...
The heat capacity and neutron powder diffraction measurements of the double perovskites La2NaB′O6 (B = Ru5+, Os5+) with S=3/2 on the B¿ reveal an incommensurate magnetic...
