High speed low power all spin logic devices assisted by negative capacitance amplified voltage controlled magnetic anisotropy effect

摘要

In this paper, we propose an all spin logic device with voltage controlled magnetic anisotropy (VCMA-ASL) and employ negative capacitance (NC) effect as a novel approach to amplify the VCMA effect. A new working strategy of 3-step operation scheme has been proposed, which reduces the energy consumption effectively as well as accelerates switching process.
