New Paper at Physical Review Research! #topological #singularities

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.

HMM 2019 @ Heraklion, Crete

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 workCollective antiskyrmion-mediated phase transition and defect-induced melting in chiral magnetic films“.

Talk on Skyrmions @ the Future Perspectives on Novel Magnetic Materials workshop

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.
