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“.
