Multifunctional Behavior of Fe-Doped Titanate-Based High-Entropy Perovskite Oxides
Abstract
High-entropy oxides have gained interest recently due to versatility and promising property that may be useful for advanced electronic applications. This research project focuses on exploring multifunctional responses of titanate-based, high-entropy perovskite oxide by Fe-doping. There are three main objectives of this research, including to obtain doping limit of Fe onto Ti-based high-entropy perovskite oxide, to elucidate structural information, and to observe electric and magnetic responses of the Fe-doped Ti-based high-entropy perovskite oxides. Preparation of (Na0.2Bi0.2Ba0.2Ca0.2Sr0.2)(Ti1-xFex)O3 ceramics is performed by solid-state reaction technique where Fe concentration is varied. Detailed structural characteristics of single-phase compound is analyzed by using X-ray diffraction, Raman spectroscopy, and synchrotron X-ray absorption techniques. Frequency and temperature dependence of dielectric and magnetization are measured to obtained multifunctional characters of the materials. The outcome of this research is anticipated to achieve multifunctional responses of electric and magnetic on a single-phase Fe-doped high-entropy perovskite oxide. It may become an alternative material for using in application such as magnetic sensors, actuator, or electronic memory devices.
