Mechanics of magnetic shape memory thin films and their applications in future engineering (Advert Reference: RDF18/MCE/CHEN)

Magnetic shape memory alloys can undergo large strain change (6% − 10%) under magneto-mechanical loadings. This large strain change is due to the martensite reorientation or phase transition induced by magnetic field and/or mechanical stresses. Recently, it is found that some polycrystalline magnetic shape memory thin films can be actuated by magnetic field (Adv. Mater., 27, 2015), while others cannot (Acta Mater., 59, 2011). Systematic studies are needed to interpret the different behaviours of magnetic shape memory thin films.

The primary goal of this research is to understand the physical mechanisms coupling the multi-physics behaviours for magnetic shape memory thin films, unveil the relationship between the macroscopic behaviours and the microstructures (magnetic domains, twin microstructures, strain patterns, textures), propose design guidelines for magnetic shape memory thin films, and explore their potential applications in future micro-electro-mechanical systems. The objectives to achieve the primary goal are to:

• develop multi-scale models from microstructural evolutions to macroscopic behaviours for magnetic shape memory thin films;
• validate models by experiments and derive from model simulations the criteria/guidelines for controlling/improving the magneto-mechanical coupling behaviours of magnetic shape memory thin films;
• design, simulate and optimize micro devices of magnetic shape memory thin films that can be used as actuators, sensors, energy harvesters or magneto-caloric cooling elements in future micro-electro-mechanical systems.
