Magnetic and electric properties of bismuth ferrite lead titanate ceramics
… which decreases in periodicity with increasing bismuth ferrite, from 840 Å for x = 0.75. At room temperature, transforming the paramagnetic tetragonally distorted powder to a G-type AFM rhombohedral phase, is observed with the application of hydrostatic pressure. Evident from neutron …

Multiferroic Bismuth Ferrite-Lead Titanate and Iron-Gallium Crystalline Solutions: Structure-Property Investigations
Recently, multiferroics-defined as materials with coexistence of at least two of the ferroelectric, ferroelastic and ferromagnetic effects-have attracted enormous research activities. In this thesis, the structure and properties of multiferrioic BiFeO3-x%PbTiO3 and Fe-x%Ga crystalline solutions …

Induced Phase Transition in Magnetoelectric BiFeO3 Crystals, Thin-layers and Ceramics
Bismuth ferrite (BiFeO₃) is a magneto-electric material which exhibits simultaneously ferroelectric and antiferromagnetic properties. We have used high-field electron spin resonance (ESR) as a local probe of the magnetic order in the magnetic range of 0-25 Tesla. With increasing magnetic field, an …

THE EFFECTS OF POTASSIUM AND SODIUM CATIONS ON THE PHASE AND MORPHOLOGY OF BISMUTH IRON OXIDE CRYSTALS
Bismuth iron oxide (BFO) crystals have potential for applications ranging from next-generation, magnetoelectricity-based electronics to photocatalysts for the breakdown of toxic chemicals. Hydrothermal synthesis (HTS) has been shown to be an attractive solution growth method for producing …

New modalities for strain engineering of lead-free perovskite ferroelectric thin films
Over the last few decades, considerable attention has been given to the development of lead-based ferroelectric systems such as PbZr1-xTixO3 due to their robust high temperature ferroelectric properties, as well as the presence of the so-called morphotropic phase boundary (MPB) ̶ a …

X-ray scattering studies of strongly correlated materials: orbital ordering in KCuF3 and stripe-like domain structures in BiFeO3 epitaxial thin films
The results of x-ray scattering experiments on orbitally ordered KCuF3 and periodic arrays of stripe-like ferroelectric domains in epitaxial thin films of multiferroic BiFeO3 are presented in this dissertation. Both resonant soft x-ray elastic scattering and non-resonant hard x-ray elastic …
