We use time-of-flight neutron powder diffraction to examine static displacive disorder in three different pyrochlore A2B2O6O 0 compounds with Bi on the A site. The compounds (Bi1.5Zn0.5)(Nb1.5Zn0.5)O6O 0 (BZN), (Bi1.5Zn0.5)(Ta1.5Zn0.5)O6O 0 (BZT), and (Bi1.5Zn0.5)(Sb1.5Zn0.5)O6O 0 (BZS), are of interest – particularly BZN – for their high dielectric constants in the absence of any phase transit...

Tm-doped TiO2 nanoparticles were synthesized using a water-controlled hydrolysis reaction. Analysis was performed in order to determine the influence of the dopant concentration and annealing temperature on the phase, crystallinity, and electronic and optical properties of the resulting material. Various characterization techniques were utilized such as X-ray diffraction, Raman spectroscopy, X-...

Spin orbit coupling in 5d transition metal oxides such as Ir oxides is expected to be strong due to large atomic number of Ir and electron correlation strength will be weak due to large radial extension of the 5d orbitals. Hence, various anomalous electronic properties often observed in these systems are attributed to large spin-orbit interaction strength. Employing first principles approaches,...
