Abstract:

Objectives 1 Develop a synthetic technology of lead-free high frequency multiferroic composites. 2 Develop a method of fabrication of arrays of free-standing magnetoelectric or multiferroic composites. 3 Investigate wet chemistry synthesized multiferroic nanomaterials nanoparticles, nanowires, nanotubes, etc. using scanning electron microscopy SEM and transmission electron microscopy TEM to study their correlation between morphologies, composition, assembly, etc. and synthesis conditions. Meanwhile, e-beam in-situ nanolithography has been developed for multiferroic related devices fabrication. 4 Fabricate spinel and perovskite pristine phases with controllable composition and dimensionality and use them as building blocks to design magnetoelectric ceramic nanocomposites with integrated functionalities. 5 Demonstrate that the direct ME effect can be measured at nanometer-length scale by detecting the changes in the piezoresponse of a multiferroic material when subjected to the action of a magnetic field. 6 Mapping of the ME coupling through the domain imaging. 7 Estimate quantitatively the ME coupling coefficient. 8 Understand the fundamental physics of magnetoelectric interactions at nanoscale for implementation of multiferroic materials into functional devices.
