Summary: In this study, single phase Bismuth Iron Oxide (BFO) nanoparticles were successfully synthesized using the Sol-Gel method, and the effect of calcinating temperature on their crystallinity was investigated. The improvement in crystallinity was demonstrated by the growth of crystallites and the analysis of grain size using SEM and XRD. The dielectric constant of the nanoparticles was determined, showing a minimum value at higher frequency, and the temperature and frequency dependent properties were also studied. The results suggest the potential applications of the prepared BFO nanoparticles in advanced magneto and ferroelectric devices.

Summary: The room temperature ferromagnetism in Bi0.5Na0.5TiO3 materials can be strongly enhanced by modifying them with YMnO3 as solid solutions. The weak ferromagnetism in pure Bi0.5Na0.5TiO3 changes to ferromagnetism and antiferromagnetic-like with increasing YMnO3 concentration. The maximum magnetic moment is estimated to be around 28.4 memu/g for 9 mol.% YMnO3-modified Bi0.5Na0.5TiO3 as a solid solution. The addition of YMnO3 into Bi0.5Na0.5TiO3 crystals as solid solutions up to 9 mol.% leads to a reduction of the optical bandgap energy from 3.18 eV to 2.01 eV. The reduction of the optical bandgap energy and the significant enhancement of the magnetic moment in YMnO3-modified Bi0.5Na0.5TiO3 compounds are strongly related to the random distribution of Y and Mn cations in the host lattice of Bi0.5Na0.5TiO3 crystals. It is expected that this work will provide a simple way to integrate room temperature ferromagnetism into currently developed green ferroelectric materials.

Summary: A BiFeO3 film was prepared using a sol-gel method, and the effects of relative humidity on the film's capacitance, impedance, and current-voltage characteristics were explored. The capacitance of the film increased significantly from 25 to 1410 pF as the relative humidity increased from 30% to 90%. The impedance also varied greatly, indicating good hysteresis and response time. Analysis of the humidity sensitivity mechanism revealed the crucial role of water molecule adsorption at both low and high humidity, extending the potential applications of ferroelectric BiFeO3 films in humidity-sensitive devices.

Summary: The research presents a new method for producing multiferroic ceramic composites by connecting two ferroelectric ceramic materials, PBZrTiO3-based (P) and BaTiO3 (B), and zinc-nickel ferrite (F) in equal amounts. The goal of the experiment is to enhance the ferroelectric performance of the composites through pressureless sintering. Three different BPF composites with varying ferroelectric/magnetic content (95/05, 90/10, 85/15) were obtained. The crystal structure, electrical behaviors, dielectric, ferroelectric, and magnetic characteristics of the composites were extensively studied. The results demonstrate that using two ferroelectric materials improves the ferroelectric properties of the composites, with high saturation in ferroelectric hysteresis loops and high electrical breakdown strength.

Summary: Modified bismuth ferrite Bi1_xLaxFeO3 (x = 0.0, 0.025, 0.050, 0.075, and 0.01) was synthesized using the co-precipitation method, and X-ray diffraction analysis confirmed its rhombohedral crystal structure. The addition of La promoted crystal growth and increased crystallite size. Morphological analysis revealed spherical grains that agglomerated due to reduced grain size when La was incorporated at the Bi site.
