Our research focus is on magnetic materials. We are interested in microwave, magneto-optical, spintronic and left-handed properties of ferro-, ferri- and anti-ferromagnetic thin films, multilayers and nanostructures.
Such materials are highly promising candidates for a new generation of smaller, faster and energy efficient electronics for communications, data processing and storage, and for field-, substance- and bio-sensing.
The group is strong in both experiment and theory. Extensive and close co-operation between experimentalists and theoreticians within the group ensures the highest degree of research quality and completeness.
Our experimental research relies on the most advanced methods of fabrication and characterisation of magnetic materials and nanostructures. A number of experimental methods and technologies used in our research are unique in Australia. Among them are nanostructuring of magnetic films and multilayers, fabrication of microscopic microwave components, magneto-optical and SQUID magnetometry, spin-transfer torque microwave nano-oscillator technology, magneto-optical imaging, quasi-static measurements of domain wall dynamics, broadband and cavity-based ferromagnetic resonance and traveling spin wave spectroscopy.
Theoretically we are strong in both analytical and computational methods of describing the physics of magnetic materials as well as the physics of waves and oscillations in general, including non-linear waves, solitons, wave instabilities and chaos.
