Summary: This paper reports the synthesis and characterization of Ba1-xZnx(Fe1/2V1/2)O3(x = 0,0.05,0.10,0.15), including structure, dielectric, electrical, and optical properties. The formation of a single-phase orthorhombic structure is confirmed through X-ray diffraction analysis. Raman spectroscopy reveals different vibration modes, while FESEM microstructure analysis confirms a reduction in average grain size with increased Zn2+ concentration. The electrical parameters provide valuable data on conduction mechanism and structure-properties relationship. The maximum coercive field and efficiency are observed at higher Zn2+ concentration (x = 0.15). The direct band gap decreases from 3.28 to 3.10 eV with increasing Zn2+ concentration, indicating the generation of more free electrons in the conduction band and high conductivity.

Summary: Ferroelectric perovskite ceramics with desired properties, such as high permittivity, low loss tangent, high tunability, and high electric breakdown, are ideal for nonlinear transmission lines (NLTLs) to generate high-power RF signals. Barium strontium zirconium titanate (BSZT) ceramic compositions were synthesized and characterized to maximize material tunability. The composition Ba(0.97)Sr(0.03)Zr(0.2)Ti(0.8)O3 exhibited high permittivity (>12200), low loss tangent (<0.01), and exceptional tunability (~79%) near the phase temperature transition at 300 K.

Summary: This communication reports the structural and electrical properties of Bi(Fe0.85Gd0.15)O-3 ceramics synthesized via standard solid state reaction technique. The phase transition from rhombohedral to orthorhombic symmetry is revealed through powder X-ray diffraction analysis. The structural study shows the formation of a dense compact high quality sample. The average crystallite size is 38 nm. High dielectric permittivity value is observed with increasing temperature. Impedance spectroscopy analysis suggests a semiconductor nature and conductivity study confirms the presence of a correlated barrier hopping mechanism. The P-E loop study shows an enhancement in remnant polarization. Furthermore, several other interesting features are also reported in this work.

Summary: This study analyzed the compositional ordering in relaxor ferroelectrics using first-principles-based models and numerical simulations, finding that the nearest neighbor assumption can be adopted to understand the ordering by maximizing the number of unlike B-B' pairs. The research also discussed the subtle points of configuration energy degeneracy, which explains the partial disorder inherently present in such systems.

Summary: Ba(Ti0.25Zr0.25Hf0.25Sn0.25)O3 high-entropy ceramics were prepared and their dielectric and ferroelectric characteristics in association with the structures were investigated. The ceramics showed a single-phase perovskite structure as confirmed by X-ray diffraction and energy dispersive spectroscopy analysis. The materials exhibited a broad dielectric peak with strong frequency dispersion, indicating a relaxor nature due to nanoscale ferroelectric domain structures. The homogeneous microstructure contributed to reduced leakage current density and significantly improved dielectric strength, making these ceramics desirable for practical applications. Compared to similar systems, Ba(Ti1-xZrx)O3 & Ba(Ti1-xSnx)O3, the high-entropy ceramics demonstrated superior relaxor ferroelectric characteristics.

Summary: Object-oriented finite element (OOF2) analysis was used to investigate the effect of ZnO inclusions on the thermomechanical properties of NBT-6BT composites. Results showed that the depolarization temperature of the composite can be further improved by using ZnO nano-wire/nano-rods instead of ZnO nanoparticle/powder.
