Abstract
Skyrmion manipulation with VCMA can lead to small footprint nanomagnetic memory [1-2]. This talk will focus on experimental demonstration of VCMA induced nonvolatile creation and annihilation of skyrmions in an antiferromagnet/ferromagnet/oxide heterostructure film. This could provide a pathway for using intermediate skyrmion states to enable robust magnetization reversal with VCMA. We will discuss its scaling to lateral dimensions below 50 nm, oscillations > 50 GHz and application to neuromorphic computing.
