## Description

- description: Exchange bias (EB) in antiferromagnetic (AFM)/ferromagnetic heterostructures
    is crucial for the advancement of spintronic devices and has attracted significant
    attention. The common EB effect in van der Waals heterostructures features a low
    blocking temperature (Tb) and a single polarity. In this work, a significant EB
    effect with a Tb up to 150 K is observed in FePS3/Fe3GaTe2 heterostructures, and
    in particular, the EB exhibits an unusual temperature-dependent polarity-reversal
    behavior. Under a high positive field-cooling condition (e.g., ?0H ≥ 0.5 T), a
    negative EB field (HEB) is observed at low temperatures, and with increasing temperature,
    the HEB crosses zero at ≈20 K, subsequently becomes positive and later approaches
    zero again at Tb. A model composed of a top FePS3/interfacial FePS3/Fe3GaTe2 sandwich
    structure is proposed. The charge transfer from Fe3GaTe2 to FePS3 at the interface
    induces net magnetic moments (?M) in FePS3. The interface favors AFM coupling,
    and thus the reversal of ?M of the interfacial FePS3 leads to the polarity-reversal
    of EB. Moreover, the EB can be extended to the bare Fe3GaTe2 region of the Fe3GaTe2
    flake partially covered by FePS3. This work provides opportunities for a deeper
    understanding of the EB effect and opens a new route toward constructing novel
    spintronic devices.
