An design of skyrmion-based interconnect device

The topological properties of skyrmionic quasiparticles such as magnetic skyrmions and skyrmioniums enable their applications in future low-power, ultradense nanocomputing and neuromorphic systems. We propose here an all-magnetic skyrmionic interconnect, which has so far been the “missing component.” This interconnect will …

Surface roughness helps to stabilise out-of-plane spin textures in an uniformly in-plane magnetised system

We developed a surface roughness model for magnetic systems, by taking into account the space-dependent uniaxial anisotropy and Dzyaloshinskii-Moriya interaction (DMI) …

The image is captured during the field-induced magnetic transition of a skyrmion lattice in theory. The colour code indicates the component of magnetisation perpendicular to the film surface. Increasing of the magnetic field forces skyrmion diameter to expand. Then the lattice inversion occurs involving the breaking of domain alls accompained with the emergence of transient […]

Congratulations on our new paper! ‘Tunable terahertz oscillation arising from Bloch-point dynamics in chiral magnets’

It reveals that the formation/annihilation of skyrmions will give rise to an emergent electric field with the 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 studies provide a concept of directly exploiting topological singularities which may be relevant for THz skyrmion-based electronic devices …
