Research Themes
Thin Film Magnetism
Magnetic thin films are found in a wide range of devices and applications, including computer hard drives, and microelectronic-mechanical (MEMs) sensors and actuators. The continued drive to produce smaller, lighter, faster devices demands new functional magnetic thin films be developed.
Research in FMM includes magnetostrictive films for strain sensors, magnetocaloric films for on-chip refrigeration, soft magnetic films for on-chip electronics, and hard magnetic films for miniature motors.

Functional magnetic thin films
Functional magnetic films are used in a wide range of applications, from computer hard drives to micro-magnetic sensors. By controlling the film growth and composition, the functional properties can be tuned for the application. The majority of the films investigated are fabricated using DC/RF… -
Suppression of Stochastic Domain Wall Pinning Through Modified Gilbert Damping
This project investigates the stochastic behaviour of domain walls interacting at pinning sites within soft-ferromagnetic nanowires. Domain walls driven by externally-applied magnetic fields can undergo changes in their configuration. This changing structure can give rise to different… -
Soft Magnetostrictive Properties of FeCoCr Thin Film
This project are to investigate the magnetic, structure and mechanical properties of FeCo thin films alloying with different Cr at.% which aims to obtain high magnetostriction with soft magnetic properties (low coercive and anisotropy fields). These properties will be determined by means of XRD,… -
Studying The Effect of Growth Parameters On Magnetostrictive Amorphous Thin Films And Study The Mechanical Properties By Nanoindentation.
Magnetostrictive amorphous thin films are being developed for a wide range of MEMS applications, including strain sensors and magnetostrictive actuators. To achieve the sensitivities required for these applications the magnetic films used have to possess a large magnetostriction constant (>50ppm)…
