Spin-dependent scattering in 2D van der Waals ferromagnet Fe<sub>0.29</sub>TaS<sub>2</sub> and its heterostructure

ORAL

Abstract

The recent emergence of two-dimensional (2D) van der Waals ferromagnets has provided a new platform for exploring magnetism in the flatland and for designing 2D ferromagnet-based spintronics devices. In this talk, we will present the spin-scattering mechanisms in quasi-2D van der Waals ferromagnet. Via systematically measuring Fe0.29TaS2 devices with different thickness, it is found that the dominant AHE mechanism is found to be skew scattering in bulk single crystal, and the contribution from intrinsic mechanism emerges and become more relevant as the Fe0.29TaS2 thickness decrease. At the end, the spin-dependent scattering at the Fe0.29TaS2/superconductor interface will be discussed.
