Fabrication and Characterisation of Magnetocaloric Films

Project Description

Magnetocaloric materials are materials which change their temperature when a magnetic field is applied, they are used in applications such as solid state refrigerants. As MEMS devices and systems become more extensive, the requirement for more efficient cooling will become more important. This project investigates the magnetic properties of Ni-Fe-Ga as a function of composition in thin films, with the aim to see whether they could be used as a solid-state cooler in MEMS. The films will be fabricated using a co-sputtering-evaporation technique, unique to Sheffield. The structure and magnetic properties will be characterised using a range of techniques including XRD, electron microscopy, magnetometry and temperature measurements.
