Project description
Experimental Characterisation of Magneto-Electro-Mechanically Coupling Composites
Materials with magneto-electric coupling are anticipated for high end use in highly sensitive magnetic sensors and fatigue free non-volatile memory elements in electronics. In both applications the coupling between electrical and magnetic material properties has to be optimized. For sensors the present state of the art uses 2D-2D-laminates at mechanical resonance of a vibrating mechanical resonator. These permit very high sensitivity due to the differential character of the sensor. In these laminates the mechanical coupling can be described fairly easily, because most of the fields are linear and unidirectional. Memory materials cannot rely on a resonance concept because their functionality stems from remanent electric polarization and magnetization coupling. In this concept only rudimentary modeling approaches are found.
Coupling in composites is a product property which is mediated via the complex interaction in the microstructure. Very little is known about the complex fields and couplings in 0D-3D- and 1D-3D-structures. For the latter fairly simple modeling approaches are expected while the irregular field distribution in 0D-3D composites necessitates a thorough modeling and understanding of the local mechanisms in the material. On the other hand, particularly these microstructures offer largest interface areas which are necessary for an optimized mechanical transfer between the electromechanical coupling, on the one side, and the magnetostrictive coupling, on the other side. No conclusive dataset on the constitutive behavior of these materials is known. Characterizing their complex behavior is the major goal of this project in order to obtain full understanding of material behavior together with the modeling projects. We thus strive to characterize the electrical, mechanical and magnetic properties and their interactions field and later temperature-dependent. A crucial ingredient of our approach is the mechanical component. As a whole the achieved dataset will serve the complete magneto-mechano-electrical modeling of the materials.
A fundamental prerequisite for material analysis is material synthesis. Thus, around half of the project activity is devoted to material synthesis mainly of 0D-3D composites with preferably core shell structure in order to optimize the electrical field distribution within the microstructure. Materials are to be synthesized along different routes. 1D-3D and 2D-2D-compostes serve as reference for modeling. This project thus combines chemical material science approach and material analysis for an overall constitutive property characterization.
