Abstract
The unique ability of multiferroic materials to display the effect of magnetoelectric coupling, ideally at room temperature, makes them an enormous source of technological application. La-doped Bi0.9FeO3 is a well-known potential applicant to be operated in multiferroic applications but, weak magnetoelectric response is one of this material's limitations. To address this issue, a series of nanocomposites is presented here by combining them with optimized SrFe12O19 contents. The SrFe12O19 has a hexagonal crystal structure with space group P63/mmc while Bi0.9La0.1FeO3 (BLFO) possesses a rhombohedral crystal structure with space group R3m, confirmed by structural analysis. A homogenous distribution of grains in bi/phase composites was seen. Using PE loops, the ferroelectric nature of this composite is determined, revealing significant polarization, remanent polarization, and efficiency. Recoverable energy and energy loss density from the charging and discharging curves demonstrate that the composite has potential for energy storage devices. Furthermore, fast switching capability of the composites make it more prominent because it consumes less energy while switching of the polarization. In addition, the magnetic properties of the composite also enhanced which make it potential candidate for utilization into multifunctional devices.
