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 …

When Bloch point hops through magnetic multilayers

In this Letter, we theoretically demonstrate the annihilation of single skyrmions in a multilayer structure. The process is mediated by topological hedgehog singularities known as Bloch points, whose intralayer and interlayer dynamics gives rise to intriguing emergent electromagnetic fields …

Our paper entitled ‘Magnetization dynamics in synthetic ferromagnetic thin films’ is published!

(Abstract) Synthetic ferromagnets (SFMs) possess the same layer structure found in the widely studied synthetic antiferromagnets. This consists of two ferromagnetic (FM) layers separated by a non-magnetic (NM) spacer forming the structure FM1/NM/FM2, but SFMs describe the case where the interlayer exchange coupling promotes the parallel alignment of the magnetizations of the FM layers. The […]

Our novel skyrmion-based synapses have launched 🚀

We propose a nanoscale synapse based on magnetic skyrmions. We show that when such synapses in a deep spiking neural network (SNN) with supervised learning achieve ∼98.61% classification accuracy in the MNIST …
