Project Member(s): Zhu, J.

Funding or Partner Organisation: Australian Research Council (ARC Discovery Projects)

Start year: 2006

Summary: This project aims to characterise and model nanostructured soft magnetic materials for development of advanced electromagnetic devices, such as micro sensors and actuators. New characteristics under vector magnetisations will be investigated using the world first 3D magnetic testing system. Meanwhile, the magnetisation process will be observed by magneto-optical imaging in order to understand the mechanisms by relating the microscopic domain structures to the macroscopic magnetic properties. New material models will be developed and implemented numerically. This study will greatly enrich the knowledge of magnetic properties of nanostructured materials, and will enable the development of innovative smart devices and systems.
