Our recent theoretical/computational paper on “Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets” has now been published at the Physical Review Research journal! Congratulations to the lead author, our PhD student Yu Li. The work arose from a collaboration between the University of Manchester with the Metal Physics and Technology group at the ETH Zürich. This work reveals that the formation/annihilation processes of skyrmions will give rise to an emergent electric field with a frequency in the THz regime. The electric signal is due to the ultra-fast Bloch-point propagation, and both the amplitude and frequency can be tuned by the manipulation of Bloch-point dynamics. Our study provides a concept of directly exploiting topological singularities that may be relevant for THz skyrmion-based electronic devices.

Congratulations to our PhD student, Yu Li, for winning the Best Poster award at the ‘Skyrmions in Magnetic Materials‘ seminar in Bad Honnef, Germany. He presented a poster on our recent work on ‘Tuneable Bloch-point dynamics during switching of skyrmions and antiskyrmions in chiral magnets‘, which is also available on the arXiv (link).

Really excited to participate in the British-German WE-Heraeus-Seminar on ‘Skyrmions in Magnetic Materials’ at the Physikzentrum Bad Honnef (1st – 5th Dec., 2019). We participated with two of our PhD students, Yu Li and Runze Chen, who presented posters relevant to Bloch point dynamics, and neuromorphic computing, respectively.

Really excited to participate the 12th International Symposium on Hysteresis Modeling and Micromagnetics (HMM2019) in Crete, Greece from 19th-22nd of May, 2019. Yu Li, a PhD member of our team, presented a talk in the first session “Magnetic Solitons I”, with the title “Controllable THz Bloch-point propagation in the switching process of magnetic skyrmions“. We also presented a poster from our recently published work “Collective antiskyrmion-mediated phase transition and defect-induced melting in chiral magnetic films“.

Excited to participate at the Skyrmion workshop at Trinity Hall, the University of Cambridge, organised by the U.K.’s Skyrmion Project, from Tuesday 28th-Thursday 30th of August 2018. Happy to contribute a talk and participate in the panel discussion : “Prospects for Disruptive Skyrmion Technology”.

Excited to be at the the Future Perspectives on Novel Magnetic Materials workshop taking part from May 29-June 3, 2018 in beautiful Santorini, Greece. The workshop’s program focused on the development of high anisotropy magnetic materials, ii) non-collinear spin structures that exhibit skyrmion and anti-skyrmions and iii) magnetic materials that display topological transport and electronic properties. Happy to be invited to contribute a talk on Thursday the 31st of May, on recent numerical and experimental results on magnetic skyrmions.

Very interesting visit (14-16/02/2018) and discussions with Prof. Pinuaga and Prof. Banerjee at the Cognitive Systems and Materials Center, University of Groningen. Happy to participate at the Physics Colloquium with a talk “Towards Skyrmion-based Electronics”.

At the The Zernike Institute for Advanced Materials, University of Groningen.

The Introduction to the skyrmions lecture is now online! It is available at the ISOE youtube channel.

Happy to have contributed lectures on the X-ray imaging of nanostructures and Magnetic Skyrmions. The lectures were part of the International School of Oxide Electronics 2017 in beautiful Cargèse, Corsica, with two weeks of lectures on topics such as multiferroics, oxide based devices for electronics and spintronics, domain walls,oxide interfaces, topogically insulating oxides.

Excited to see our recent paper on the demonstration of nanoscale room temperature (R.T.) sub-100nm chiral skyrmions, with the Paul Scherrer Institut and CNRS/Thales, ( Nature Nanotechnology. 11, 444–448 (2016) ) selected as a leading paper. The selection highlights papers from across the University of Manchester’s Faculty of Science and Engineering. The highlight describes the discovery of room temperature individual nanoscale chiral skyrmions by means of high resolution X-ray imaging. The research was performed in the context of the MAGicSky EU research project and this observation can enable further fundamental studies on the very rich physics of skyrmions as well as serve as a basis for the development of skyrmion-based memory and logic devices.
