Abstract

As an all-electrical scheme to generate, detect and manipulate spin current, the spin Hall effect (SHE) has been heavily investigated as a primary route towards next-generation spintronic devices. SHE-enabled readout of magnetic states (spin states) is central to the operation of energy efficient spin logic device. However, the spin readout signal of nanomagnets based on SHE in heavy metals, which is typically less than 10 mΩ, falls severely short of the operation standards in practical spin logic devices. In this talk, I will discuss our recent efforts of achieving highly efficient read out of 2D ferromagnetic states with topological semimetals. Our demonstration paves the way for integrating 2D ferromagnets into future memory and logic devices.
