The dissertation focuses on analyzing the influence of synthesis temperature and doping materials on the structure, dielectric, and magnetic properties of lead ferrite (Pb2Fe2O5) thin films synthesized by the reactive magnetron deposition method. Multiferroics, characterized by possessing multiple primary ferroic properties, hold great potential for advanced computer memory technologies, sensors, photovoltaic technologies, and high-tech electronics. Among various approaches, doping presents an effective method for modifying parameters of thin films, including remnant polarization, magnetization, and their interrelationship. The study investigates thin films of lead ferrite doped with transition metals (chromium, cobalt, niobium, and nickel), synthesized using the reactive magnetron deposition method at synthesis temperatures ranging from 500 to 600 °C. The research findings demonstrate that the doped PFO thin films exhibit ferroelectric and magnetic properties at room temperature. Manipulating the concentration of dopants and adjusting the synthesis temperature enables the amplification of remnant polarization and the alteration of thin film growth dynamics. Furthermore, the study highlights the significant influence of synthesis temperature on the efficient formation of PFO phases, resulting in improved ferroelectric and magnetic properties. |
