| It is well known that, unlike single phase multiferroics, in composites the different ferroic orders do not necessarily have to coexist in the same phase. In contrast, when working with multiferroic composites, and more specifically with layered composites, a large extrinsic coupling at the interface and therefore a high volume of interfaces between the different materials represents an important parameter. This can be currently achieved, more or less effortlessly, by applying processing techniques such as PLD, CVD, MBE or RF sputtering, which hallow a high degree of crystallographic control. Despite the effectiveness of these techniques, they all involve high energy consumption in terms of temperature and/or vacuum, so replacing them by sustainable processing alternatives would be very interesting. In this frame a simple sol-gel plus spin-coating methodology is here proposed to prepare thin film composites of the potentially multiferroic BiFeO3-Bi4Ti3O12 system. Furthermore, an aqueous solution-gel routine is employed to avoid the use of typical organic solvents in a conventional sol-gel method, so further persisting on the sustainability concept. As it will be described, attempts are conducted that eventually demonstrate how by controlling the processing parameters it is possible to obtain a high volume of interfaces between dissimilar materials. | |
