Overview

My research interests lie in magnetic materials, spintronics and photonics, with particular emphasis on ultrafast and high frequency processes. My research group uses a combination of microwave and time resolved optical and x-ray measurement techniques to study structural, electrical and magnetic changes in condensed matter systems. Our research is directly relevant to different forms of data storage technology, including hard disk drives, magnetic random access memory (MRAM) and phase change recording, also to new paradigms for data processing such as neuromorphic computing and magnetics based logic.

PhD Supervision

I have supervised more than 20 PhD students and welcome enquiries from self funded students.  Applications for projects in the following areas are particularly welcome:

• All-optical magnetic switching for ultrafast data storage
• Synchronization of spin transfer oscillators for neuromorphic computing
• Amplification of spin current within antiferromagnets
• Spin torque for switching magnetic random access memory and excitation of spin waves
