## Description

- description: In this work we report efficient out-of-plane spin injection and detection
    in an all-van der Waals based heterostructure using only exfoliated 2D materials.
    We demonstrate spin injection by measuring spin-valve and Hanle signals in non-local
    transport in a stack of Fe3GeTe2 (FGT), hexagonal boron nitride (hBN) and graphene
    layers. FGT flakes form the spin aligning electrodes necessary to inject and detect
    spins in the graphene channel. The hBN tunnel barrier provides a high-quality
    interface between the ferromagnetic electrodes and graphene, eliminating the conductivity
    mismatch problem, thus ensuring efficient spin injection and detection with spin
    injection efficiencies of up to P = 40 %. Our results demonstrate that FGT/hBN/graphene
    heterostructures form a promising platform for realizing 2D van der Waals spintronic
    devices.
