Our research lies at the intersection between nanomagnetism and topology. Our main scientific interests pertain to nanomagnetism and topology, magnetic skyrmions, spin-orbit coupling effects, skyrmion-based devices and X-ray imaging. We explore the rich physics of skyrmions and their technological applications (“Skyrmionics”),  Spin-Orbit Coupling effects (“Spin-orbitronics”) and in general in the field of Spintronics. Specifically, we focus on enabling next-generation unconventional computing by investigating nanocomputing and neuromorphic computing. 

Some of our contributions include the observation of skyrmion bubble states and topologically trivial states and predictions on the dynamics of skyrmionic configurations, the demonstration of the gigahertz eigenmode dynamics of skyrmion bubbles and their unexpectedly large inertia and the observation of nanoscale skyrmions at room temperature. We recently proposed a nanoscale room-temperature multilayer skyrmionic synapse for deep spiking neural networks.

Post-doctoral Research Associates

  • Dr. Will Griggs

Will is a postdoctoral experimentalist whose work focuses on skyrmionic systems for brain-inspired computing. In particular, he is working to build nanoscale artificial synapses which use skyrmions as information carriers, paving the way towards high-performance machine learning applications with extremely low power budgets. Will uses a diverse range of experimental techniques for the fabrication and characterisation of nanoscale devices, including magnetron sputtering, photo- and e-beam lithography, X-ray diffraction/reflectometry, vibrating sample/SQUID/MOKE magnetometry, scanning probe microscopy, ferromagnetic resonance, and polarised neutron reflectometry. He received his PhD from the University of Manchester in 2020 working on interfacial engineering in thin-film composite multiferroics. Will is working on the Skyrmionics for Neuromorphic Technologies project.

PhD students

  • Yuzhe Zang

PhD student in Computer Science at the University of Manchester

Supervisor: Dr. Christoforos Moutafis
Co-supervisor: Prof. Tom Thomson

Yuzhe’s  research interests are centred around behaviours of skyrmions in multilayer thin films and confined nanosturctures. Currently, Yuzhe is looking for a more energy-efficient method to manipulate skyrmions, assisting further development of skyrmion-based neuromorphic devices. Yuzhe employs both experimental and simulation methods to study skyrmions in multilayers and nanostructures. This includes: multilayer thin film engineering, in which sub-nanometre Co layers were deposited and characterised; fabrication and characterisation of multilayer nanodots arrays with the smallest diameter down to 200 nm; micromagnetic simulation of evolution of magnetic skyrmions and domains in thin films and nanostructures.

  • Yu Li

Yu LiPreviously a PhD student in NEST Group, Department of Computer Science, and my project was supervised by Dr. Christoforos Moutafis, and Prof. Jim Miles.

My recent research interests lie in the theoretical&computational studies of magnetic skyrmions, and vary between many topics, e.g. skyrmion/antiskyrmion switching in chiral magnets, 3D dynamics and the energy landscapes of switching processes, roughness effect on the stability of skyrmionic textures in multilayer structures, ferromagnetic resonance, skyrmion-based devices, etc. I’m also having board collaborations with many people working on experiments, including people in our NEST group @Manchester, ETH Zurich, and Paul Scherrer Institute (PSI).
