Multiferroic Materials Development and Applications
Ferroic materials have been of interest for decades as some of the most important functional materials classes that are of interest for a wide range of applications, and transduction in particular, due to the strain that develops with applied magnetic or electric fields. Recently, combining these materials into multiferroic composites has created a path for many innovative devices by utilizing the coupling between magnetic and ferroelectric order parameters. At NRL, we are advancing these materials and exploiting this coupling for a number of applications. In this talk, fundamental research will be presented on improving the figure of merit by evaluating single phase multiferroics or artificial multiferroic heterostructures with new functionalities, and examine the implications for low power magnetic field sensors, vibrational energy harvesting, and wireless power transfer and low-frequency transmitters. A future outlook on multiferroics devices relevant to the Navy will also be discussed.
