In line with the trend towards electrification in mobility, there is a demand for development of next-generation Multilayer Ceramic Capacitors(MLCCs) superior properties compared to those using conventional BaTiO<sub>3</sub> (BT) ceramics. For this, various high-performing ferroelectric ceramics have been proposed as post-BT materials, and numerous studies conducted on role oxygen v...
Electronic properties of CaTiO3 crystal in paraelectric and ferroelectric phases have been studied by first principles, using Hohenberg-Kohn-Sham density functional theory (DFT). In paraelectric phase the results show an indirect band gap of about 2eV at -R direction in the Brilluoin zone and a strong hybridization between Ti-3d an O-2P orbital. In ferroelectric phase a direct band gap of abo...
Abstract The paper analyzes the influence of hard and soft admixture on functional properties multiferroic ceramic composites. Two composite materials via solid-state reaction route were obtained. PZT-type (with or admixture) selected as ferroelectric component (90%), nickel–zinc ferrite magnetic (10%). doping type (soft component) composites’ dielectric, ferroelectric, electromechanical, magne...
