Rate My Professor R. J. Hicken

Professor R. J. Hicken holds the position of Professor in the Department of Physics and Astronomy at the University of Exeter, where he also serves as Director of Research. His research centers on magnetic materials, spintronics, and photonics, placing particular emphasis on ultrafast and high-frequency processes. The research group led by Professor Hicken utilizes a combination of microwave techniques and time-resolved optical and X-ray measurement methods to examine structural, electrical, and magnetic transformations in condensed matter systems. This work has positioned him as a key figure in advancing the understanding of dynamic phenomena in magnetic nanostructures and thin films.

Professor Hicken has authored numerous influential publications that have shaped the fields of magnonics and ultrafast magnetization dynamics. Among his seminal contributions is 'Magnonics: Experiment to prove the concept' published in the Journal of Magnetism and Magnetic Materials in 2006 with V. V. Kruglyak. Other notable papers include 'Imaging collective magnonic modes in 2D arrays of magnetic nanoelements' in Physical Review Letters in 2010, 'Picosecond magnetization dynamics in nanomagnets: Crossover to nonuniform precession' in Physical Review B in 2005, and 'Direct detection of pure ac spin current by x-ray pump-probe measurements' in Physical Review Letters in 2016. Earlier works such as 'Observation of ferromagnetic resonance in the time domain' in Optics Letters in 1999 and 'Vectorial magnetometry with the magneto-optic Kerr effect applied to Co/Cu/Co trilayer structures' in Physical Review B in 1993 demonstrate his longstanding expertise in time-resolved magneto-optical spectroscopy and ferromagnetic resonance. His research outputs exceed 160 items, with collaborations spanning international institutions, contributing significantly to spin wave propagation, spin current detection, and applications in spintronic devices. Professor Hicken is associated with the Centre for Metamaterial Research and Innovation at Exeter and engages in public outreach through events like Pint of Science.
