Identification of anti-ferromagnetically coupled skyrmion pairs for quasi zero power computing: emulation of biological neuron/synapse functions
Abstract
To emulate the functionality of biological neuron/synapse operating at ultralow power and ultrafast speed has become an essential ingredient for high performance Artificial Intelligent (AI) computing. Thus, various approaches have been proposed by adapting phase change, ion drift, and magnetization switching dynamics under various electrical pulses. However, the current existing dynamics still suffer from the unacceptable instability arising from its intrinsic mechanism and similar order of operating power density, compared to the conventional CMOS devices. Therefore, this project is to promote the anti-ferromagnetically coupled magnetic skyrmion pair (AFC-SkP)-driven neuron and synapses functions that make a breakthrough for implementing future low-power high-density neuromorphic computing systems. The scientifically innovative point of this project is to bring an anti-ferromagnetic coupled triple layer frames for the generation AFC-SkP working as information carriers for neuromorphic computing units, along with interface engineering process by engaging remote off-axis plasma radicals. This idea is based on the antiferromagnetic Ruderman-Kittel-Kasuya-Yosida (RKKY) coupling of two FM layers for the compensation of the topological number to provide a straight stable shifting for AFC-SkP
