Ahoy!
I am a Dame Kathleen Ollerenshaw fellow in the Department of Computer Science at The University of Manchester, working in the Nano-Engineering and Spintronics Technologies research group. I am also a member of the NeuroSky team. My research interests include spintronics, magnonics, and skyrmionics for unconventional computing.
PhD Students
I am looking to work with skilled, motivated PhD students with a background in experimental or computational condensed matter physics, or neuromorphic computing. If this is you, please get in touch. I am currently advertising a fully-funded PhD position for UK students here.
Selected Work
Encoding and multiplexing information signals in magnetic multilayers with fractional skyrmion tubes
R. Chen, Y. Li, W. Griggs, Y. Zhang, V. F. Pavlidis, and C. Moutafis.
We explore the potential of fractional skyrmion tubes (FSTs) to be used as magnetic information carriers in unconventional computing. We use micromagnetic simulations to demonstrate that it is possible to nucleate and stabilise FSTs with different depth profiles in a single interconnect device which supports automatic signal demultiplexing.
W. Griggs, B. Eggert, M. O. Liedke, M. Butterling, A. Wagner, U. Kentsch, E. Hirschmann, M. Grimes, A. J. Caruana, C. Kinane, H. Wende, R. Bali, and T. Thomson.
We demonstrate control of the magnetic ordering in FeRh with depth selectivity via irradiation with light noble gas ions, and elucidate the relationship between the type and concentration of induced defects to the observed magnetic modifications.
humbleBragg is a free, web-based X-Ray diffraction (XRD) simulator, with support for several common scan geometries, reciprocal space mapping, CIF import, and Crystallography Open Database lookup. Calculations can be performed for powders, single crystals, or textured samples.
