Pyrochlore to Defect- Fluorite Transition Studies in Holmium-Titanate based Composition using Neutron Powder Diffraction Technique-3

The aim of this experiment is to determine high quality structural models for pyrochlore and zirconolite phases in the Y2Ti2-2xFexNbxO7 and Y2-xCexTi2-xFexO7 solid solutions,...

Silica-free barium titanate bulk glasses, containing lanthanide elements, show unusually high dielectric response and a high refractive index. These properties allow crucial...

Geometrical frustration in the spin ice material Dy2Ti2O7 leads to macroscopic degeneracy and the observation of magnetic diffuse neutron scattering down to the lowest...

Excitations in spin ice fractionalize into de-confined magnetic monopoles that interact with each other via the magnetic Coulomb interaction. Substituting rare earth ions with...

We want to investigate and Rietveld-refine the crystal structures of a number of lithium titanates and niobates of interest as battery anode materials. Some of these phases have...

Pyrochlore to Defect- Fluorite Transition Studies in Holmium-Titanate based Composition using Neutron Powder Diffraction Technique-2

The polycrystalline ceramic BiFeO3 - PbTiO3 is both ferroelectric and antiferromagnetic for a wide range of compositional space. We have shown in previous experiments that (1)...
